Requirements for Upgrading

Your hardware and software environment must meet the following requirements before you can upgrade to the latest Cisco MGC software release:

Table 6-1 Requirements for Upgrading

Requirement
Description

Disk requirements

Minimum of 2 disks

Disk size

Minimum of 18 GB

Operating system

Solaris 8 operating system

Note If you are running Cisco MGC software release 7.4(x) or 9.1(5), you must first upgrade your operating system to Solaris 8 and the latest patches.

Patch levels

Install the latest patch versions on both the Active and Standby hosts. Refer to Cisco.com to determine the latest patch versions available.

pom.dataSync parameter setting

Located in the XECfgParm.dat file. Set the pom.dataSync parameter to false when upgrading from a patch level that does not support Seamless Upgrade to a patch level that supports it. Otherwise, the standby system will not transition to the standby state and will remain out-of-service (OOS).

Installer requirements

•Experienced Solaris system administrator.

•Familiarity with system administration tasks such as mounting file systems and running tar to save and restore files.


Note Before starting the upgrade, obtain a remote server IP address from your system administrator. A remote file server is required when backing up configuration data (see Step 4 in the "Backing Up the Configuration Data" section.

Quick Guide to Upgrading Your Cisco MGC Software

Caution Always start migration from the standby box (Host B).

The following table provides a guide to upgrading to the latest Cisco MGC software release. For details, refer to the page numbers located on the right-hand column of the table.


Before You Begin

You can do limited provisioning while upgrading from Cisco MGC software releases 9.x. Limited provisioning means you can provision the following during the upgrade or downgrade period:

–Screening configuration

–Ported numbers

–Number termination

–Advice of Charge (AOC)

–A number dial plan selection

Caution Do not make any provisioning changes while upgrading from Cisco MGC software releases 7.4(x) or 9.x to the latest software release.

Note Contact Cisco TAC if you need assistance (see the "Obtaining Documentation, Obtaining Support, and Security Guidelines" section on page xvii).

If You are Upgrading from Cisco MGC 7.4(x)

Step 1 If you are not using any screening data (AWHITE, ABLACK, BWHITE, BBLACK), proceed to Step 2 prior to uninstalling Cisco MGC 7.4(x).

If you are using screening, perform the procedure in Step 3 following after restoring the configuration data, as described in Chapter 2, "Sun Solaris 8 Operating System Installation," and prior to installing Cisco MGC release 9.x.

Step 2 Remove the .ttdb files from the /opt/CiscoMGC/etc directory. Enter the following command to cause a complete installation of the TimesTen database instead of an upgrade. 

rm /opt/CiscoMGC/etc/*.ttdb

The procedure is complete.

Step 3 Enter the following commands prior to uninstalling 7.4(x) for each customer group ID that you have data for—this will create export files of your data that can later be re-imported: 

prov-add:files:name="awhitefile", file="XXXX.awhite", action="export 

prov-add:files:name="bwhitefile", file="XXXX.bwhite", action="export 

prov-add:files:name="ablackfile", file="XXXX.ablack", action="export 

prov-add:files:name="bblackfile", file="XXXX.bblack", action="export

Where XXXX is a customer group ID (dialplan name).

Step 4 After the installation of the Cisco PGW is complete you can provision the data again (if necessary) by doing the following for each of the export files created prior to the uninstallation of Cisco MGC release 7.4: 

prov-add:files:name="awhitefile", file="XXXX.awhite", action="import 

prov-add:files:name="bwhitefile", file="XXXX.bwhite", action="import 

prov-add:files:name="ablackfile", file="XXXX.ablack", action="import 

prov-add:files:name="bblackfile", file="XXXX.bblack", action="import

The procedure is complete.

If You are Upgrading from a Cisco MGC 9.x Release to Another 9.x Release

You must run the current Cisco MGC 9.x uninstall script before upgrading to or downgrading from another Cisco MGC 9.x version.

Note You must run the uninstall script of the current Cisco MGC 9.x version to avoid upgrade problems.

Back Up Your Software

Step 1 Verify that there are no existing major alarms. Log in to both Host A (active box) and Host B (standby box) and enter the following MML command: 

rtrv-alms

If major alarms are found, resolve the problems first before proceeding with the upgrade.

Step 2 Before migrating from Cisco MGC software release 9.x prior to 9.4(1), you must first back up the /opt/SW directory.

a. To ensure that you do not lose the contents of the /opt/SW directory, create a sub-directory under /opt/SW/9.x directory name and save the contents there. This will provide you a copy of the originally-installed 9.x patches, in case you need to fall back to it.

b. Remove the .pkg files from the /opt/SW directory before proceeding with the upgrade.

Step 3 Save the configuration data in both Host A and Host B. To create an mgc-backup folder under /tmp, log in as mgcusr and enter the following commands: 

mkdir /tmp/mgc-relnum-backup

mgcbackup -d /tmp/mgc-relnum-backup

Where relnum is the current software release number.

For example, to save the configuration data for a system running Release 9.4(1), you would enter the following commands: 

mkdir /tmp/mgc-941-backup

mgcbackup -d /tmp/mgc-941-backup

Step 4 Copy the XECfgParm.dat file. Enter the following command: 

cp /opt/CiscoMGC/etc/XECfgParm.dat  /tmp/mgc-relnum-backup/XECfgParm.dat.relnum

Where relnum is the current software release number.

For example, to copy the XECfgParm.dat file for a system running Release 9.4(1), you would enter the following command: 

cp /opt/CiscoMGC/etc/XECfgParm.dat  /tmp/mgc-941-backup/XECfgParm.dat.941

Step 5 Copy the files in the mgc-relnum-backup folder to a remote file server using the FTP file transfer utility. Type the following command to FTP the files to a remote server and press Enter: 

ftp remote_server_IP_address

Note The remote server IP address is provided by your system administrator.

Make sure that you are in binary mode before you FTP your files.

Step 6 If you are using MMDB, do the following steps:

a. Verify that both the Active and Standby hosts have the latest Cisco MGC 9.x system patch.

b. Log in as mgcusr and type the following command in both the Active and Standby Hosts, then press Enter: 

./mod_replication_port.sh

c. If you are upgrading to Release 9.6(x) from Release 9.3(x), 9.4(x), or 9.5(x), type the following command in both the Active and Standby Hosts, then press Enter: 

./delete_replication.sh

Check for Mated STP Pairs

Before upgrading the standby host (Host B) to Cisco MGC 9.3(2), check if Mated Signal Transfer Point (STP) pairs are currently configured on the system.

On the active host (Host A), type the following MML command and press Enter to retrieve the provisioning information for all the SS7SUBSYS: 

prov-rtrv:ss7subsys:"all"

Following is an example of the text that is displayed. Look for STP entries in the MATEDAPC column in the text display. 

va-seattle mml> prov-rtrv:ss7subsys:"all"

   MGC-01 - Media Gateway Controller 2003-06-16 23:15:18.093 EST

   */

   ;

a. If Mated STP pairs are configured on the SS7SUBSYS, they are displayed in the MatedAPC column: You must create routes for the mated pairs before proceeding with the upgrade. Follow the procedures in the "Add an SS7 Route for Each Mated STP (from Release 7.4(x) only)" section.

b. If Mated STP pairs are not configured on the SS7SUBSYS, the MatedAPC column is blank: Continue to the "Check for ^M Characters in XECfgParm.dat" section, below.

Add an SS7 Route for Each Mated STP (from Release 7.4(x) only)

To ensure a seamless upgrade from Cisco MGC 7.4(x), one SS7 route is required for each STP if the STP is mated.

On the active host (Host A), do the following procedures to add a route for each mated STP:

Step 1 Find the OPC, DPC and linkset names that are associated with STPs. Type the following MML command and press Enter: 

prov-rtrv:ss7route:"all"

Text similar to the following is displayed: 

   MGC-01 - Media Gateway Controller 2003-06-16 23:22:42.542 EST

M  RTRV

   "session=932-Japan-9:ss7route"

   /*

route-stp2     opc-sc2200    stp2        ls2         1         

   */

   ;

Step 2 Start a provisioning session. Type the following command and press Enter: 

prov-sta::srcver="active" dstver="newconfig"

Step 3 Create priority 2 SS7Routes to the "SVC"s (SERVICE) through the corresponding MATEDAPCs, as shown in the following example.

In this example, the following provisioning command is entered to create an SS7 route to SVC (stp1) via MATEDAPC (mateStp): 

prov-add:ss7route:name="rte-to-stp1",desc="Route to stp1 via mated STP",opc="opc1", 
dpc="stp1",lnkset="ls-to-mateStp",pri=2

Where:

ls-to-mateStp = the MML name of the previously provisioned linkset to "mateStp"

opc1 = the MML name of the OPC associated with linkset to "mateStp"

Example:

The following example is based on the output above. One route for each STP is needed. 

prov-add:ss7route:name="route-stp1",desc="Route to stp1 via mated STP",opc="opc-pgw2200 ", 
dpc="stp1",lnkset="ls2",pri=2

prov-add:ss7route:name="route-stp2",desc="Route to stp2 via mated STP",opc="opc-pgw2200 ", 
dpc="stp2",lnkset="ls1",pri=2

Step 4 Deploy the configuration changes done in Step 3 (above), to the STANDBY platform by typing the following command: 

prov-dply

Step 5 Type the following command to execute a MML command on ACTIVE platform: 

sw-over::confirm

Step 6 Wait about 10 minutes then make sure the platforms have switched to ACTIVE/STANDBY.

Step 7 Perform a manual switchover using the sw-over::confirm MML command on the ACTIVE platform.

Step 8 Follow normal upgrade process to upgrade the STANDBY platform to the latest software release.

Step 9 To complete the upgrade process, go to Step 2 on page 6-8.

Check for ^M Characters in XECfgParm.dat

Before you perform backup procedures on your configuration data, make sure to remove ^M characters (Ctrl-m or carriage return) at the end of each line in the file. The ^M characters may be present if the XECfgParm.dat file was modified by a Microsoft Windows (DOS)-based editor like Notepad.

If you do not remove the ^M characters, you might get an error similar to the following when you install the new software version: 

ttRestore: SQL Error: Failed to connect to data store

There are two ways to remove ^M characters and avoid this error. Before backing up your configuration data, perform one of the following procedures:

•Run the dos2unix utility. For instructions, see Running the dos2unix Utility.

•Edit the XECfgParm.dat file with the vi editor. For instructions, see Editing the XECfgParm.dat File.

Running the dos2unix Utility

To run the dos2unix utility to remove ^M characters, perform the following steps before backing up your configuration data:

Step 1 Set your directory to the location of the XECfgParm.dat file by entering the following command: 

cd /opt/CiscoMGC/etc

Step 2 Move the XECfgParm.dat file by entering the following command: 

mv XECfgParm.dat XECfgParm.dat.old

Step 3 Run the dos2unix utility by entering the following command: 

dos2unix XECfgParm.dat.old XECfgParm.dat

Step 4 Using the vi editor, verify that all the ^M characters have been removed from the XECfgParm.dat file.

Editing the XECfgParm.dat File

Check for the presence of a ^M character before starting the upgrade. If found, perform the following steps before backing up your configuration data.

Step 1 Set your directory to the location of the XECfgParm.dat file by typing the following command: 

cd /opt/CiscoMGC/etc

Step 2 Edit the XECfgParm.dat file with the vi editor by typing the following command: 

vi XECfgParm.dat

Step 3 Execute the following command in the vi editor to remove the ^M character from the end of each line. 

1,$s/^v^m$//

Where:

^v is Ctrl-v

^m is Ctrl-m

There is no space between //.

Step 4 Save the changes and exit vi.

Continue to the following section, "Upgrading the Cisco MGC Software Release".

Upgrading the Cisco MGC Software Release

Note Both the active host (Host A) and standby host (Host B) must be running either Cisco MGC software release 7.4(x) or 9.x.

Note If you are upgrading from Cisco MGC release 7.4(x) and using screening data (such as AWHITE, ABLACK, BWHITE, BBLACK), you must first see the "If You are Upgrading from Cisco MGC 7.4(x)" section.

To upgrade to a later Cisco MGC software release:

Step 1 On both Host A and Host B, make sure that pom.dataSync is set to False. Use an editor such as vi to edit the /opt/CiscoMGC/etc/XECfgParm.dat file and set this value.

Step 2 On Host B, log in as root. Enter the following command to stop the Cisco MGC and shut down Host B: 

/etc/init.d/CiscoMGC stop

Step 3 On Host B, install the latest available system and protocol patches for the system you are running. Refer to the Release Notes for the Cisco Media Gateway Controller Software Release x (release version of the software you are running) for the patch location and installation procedure.

Step 4 Start Host B. Type the following command and press Enter: 

/etc/init.d/CiscoMGC start

Step 5 Make sure that the replication of call states is occurring between Host A and Host B are now running the latest patches.

To verify whether replication of call states is occurring between Host A and Host B, enter the following MML command: 

rtrv-cic:<ss7sigpath>:cic=<cicno>

Step 6 Perform a manual switchover on Host A. Let Host B (the standby host running Cisco MGC 7.4(x) or 9.x and the latest patch) take over and become active. Enter the following command: 

sw-over::confirm

Step 7 Check to make sure that Host B is processing calls.

Step 8 Wait until Host A becomes standby. Shut down Host A.

Step 9 On Host A, log in as root. Enter the following command to stop the Cisco MGC: 

/etc/init.d/CiscoMGC stop

Text similar to the following example is displayed: 

[ output = "TimesTen Release x.y.z build time ... ]

Step 6 Replace the "TimesTen Release x.y.z" with the version output. Type the following command and press Enter: 

echo xyz >/opt/CiscoMGC/etc/version.ttdb

Step 7 Verify that the backup is successful. Type the following commands and press Enter to make sure that the version.ttdb, migrate.ttdb, and export.ttdb files are present: 

cd /opt/CiscoMGC/etc

ls *.ttdb

Continue to the following section, "Backing Up the Configuration Data".

Backing Up the Configuration Data

To back up the configuration data:

Step 1 Log in as root.

Step 2 If you are upgrading from Release 7.4(x), save the snmpd.cnf file located in /opt/CiscoMGC/snmp in another directory. Enter the following command: 

cp /opt/CiscoMGC/snmp/snmpd.cnf  /opt/CiscoMGC/dialPlan

Step 3 Enter the following commands to back up the etc and dialPlan folders: 

cd  /opt/CiscoMGC

mkdir upgrade-backup

tar cvf /opt/CiscoMGC/upgrade-backup/MGC.tar ./etc ./dialPlan

Note The mkdir upgrade-backup command is used to create a new folder in /opt/CiscoMGC.

Step 4 Type the following command to FTP the files to a remote server and press Enter: 

ftp <remote server IP address>

Note The remote server IP address is provided by your system administrator.

Text similar to the following is displayed:

Step 10 Install the Solaris 8 operating system on Host A if you are upgrading from Release 7.4(x). If not, skip this step. For the Solaris 8 operating system and Solaris patches installation procedures, refer to Chapter 2, "Sun Solaris 8 Operating System Installation".

Continue to the following section, "Restoring Data Files".

Restoring Data Files

Do the following to restore data files:

Step 1 Log in as root.

Step 2 Enter the following command to move the configuration files to the tmp folder: 

cd /tmp

mkdir saved

cd /tmp/saved

Step 3 Enter the following commands to restore the data files:

a. From the local tape drive: 

tar xvf /dev/rmt/0

b. From a remote file server:

Using FTP, copy the file MGC.tar from a remote file server to the /tmp/saved folder.

Note You must use the binary mode of FTP and verify that the files are successfully transferred to the /tmp/saved folder before continuing to restore data files.

Step 4 You may need to create the CiscoMGC directory. To do this, enter the following commands: 

cd /opt

mkdir CiscoMGC

cd /opt/CiscoMGC

cp /tmp/saved/MGC.tar MGC.tar  

tar xvf MGC.tar

Step 5 Type the following command and press Enter to verify that both the etc and dialPlan folders are present: 

ls

Step 6 Log in as root.

Step 7 Download the latest installation script (patch) to the /opt/SW directory. Install the Cisco MGC software release and the latest patches on Host A.

For Cisco MGC software installation procedures, refer to the Chapter 3, "Cisco MGC Software Release 9 Installation." For patch installation procedures, refer to the Release Notes for the Cisco Media Gateway Controller Software Release 9.x.

Caution Do not add to your provisioning data until both of your PGW hosts have been upgraded to the current Cisco MGC software release.

Step 8 If you are upgrading from Release 7.4(x), enter the following command to move the saved snmp.cnf file back to the correct directory: 

mv /opt/CiscoMGC/dialPlan/snmpd.cnf /opt/CiscoMGC/snmp/snmpd.cnf

Note When you install the latest release of the Cisco MGC software, the existing snmpd.cnf file is renamed and a new empty snmpd.cnf file is created. The command above assumes that you backed up the old snmpd.cnf file as described in Step 2 of the "Backing Up the Configuration Data" section. If you did not back up the old snmpd.cnf file, you can delete the new empty file and rename the snmpd.cnf.custorig file to snmpd.cnf to restore your old SNMP configuration.

Caution When you upgrade your Cisco MGC software with patches or the newest release, there may be changes to the SNMP configuration file. After an upgrade, ensure that the snmpd.cnf file is still properly configured for your system. If you find that it is not, contact the Cisco TAC. You can find information on contacting the Cisco TAC in the "Obtaining Documentation, Obtaining Support, and Security Guidelines" section on page xvii.

Step 9 Verify that the Cisco MGC software release installation on Host A is successful by using an editor (such as vi) to check that there are no errors in the /var/adm/MGC_install.log file.

a. If the upgrade is successful: Continue to b.Step 10.

b. If the upgrade is not successful: Continue to the "If Migration Fails" section then return to Step 10 on page 6-13 to continue the upgrade process from Cisco MGC 7.4(x) to 9.x.

Caution If you are upgrading from Release 7.4(x) to Release 9.5(2), and you are going to use the config-lib tool to copy your Release 7.4(x) configuration to your Release 9.5(2) production, you must manually convert your XECfgParm.dat file to support Release 9.5(2) by performing the steps below once you have finished using config-lib and before you restart the Cisco MGC software.

1. Copy your Release 9.5(2) XECfgParm.dat file to a new filename. For example:

cp /opt/CiscoMGC/etc/XECfgParm.dat /opt/CiscoMGC/etc/9.5_XECfgParm.dat

2. Copy your Release 7.4(x) XECfgParm.dat file from the Configuration Library to the production
directory. For example:

cp /opt/CiscoMGC/etc/CONFIG_LIB/new/XECfgParm.dat /opt/CiscoMGC/etc/XECfgParm.dat

3. Compare the content of the original Release 9.5(2) XECfgParm.dat file to your new production
XECfgParm.dat file. Make note of parameters that are supported in Release 9.5(2) that are not in
your production file.

4. Edit your production XECfgParm.dat file (using a tool such as vi), adding the parameters to the file
that are supported in Release 9.5(2).

Step 10 Start the Cisco MGC software on Host A. Type the following command and press Enter: 

/etc/init.d/CiscoMGC start

Step 11 Verify that the configuration is migrated to the desired Cisco MGC 9.x software release on Host A and ensure that all states are operational by entering the following MML commands: 

rtrv-ne

rtrv-tc:all

rtrv-dest:all

rtrv-c7lnk:all

rtrv-iplnk:all

Step 12 Make sure that replication of call states is occurring between Host B (the active host running Cisco MGC 7.4(x) or 9.1(5) and the latest patch) and Host A (the standby host running the Cisco MGC 9.3(2) or later software release). Enter the following command on the standby host (Host A): 

rtrv-tc:all

Step 13 Perform a manual switchover on Host B (the active host). Type the following command and press Enter: 

sw-over::confirm

Step 14 Let Host A take over and become active.

Step 15 Verify that Host A (running Cisco MGC 9.3(2) or later software release) is processing calls. Type the following command and press Enter: 

rtrv-tc:all

Note If the call replication fails, or if Host A is not processing calls, refer to the "Cisco Media Gateway Controller Operations, Maintenance, and Troubleshooting Guide" for procedures on how to resolve the problem. Call Cisco TAC if you require further assistance.

To downgrade to a previous software release, see the section "Downgrading the Cisco MGC Software Release" section.

Step 16 Back up the MMDB. Refer to the "Backing Up the Main Memory Database" section for backup procedures.

Step 17 Back up the configuration data. For backup procedures, refer to the "Backing Up the Configuration Data" section and follow Step 1 through Step 8.

Step 18 Shut down Host B (the standby host running Cisco MGC 7.4(x) or 9.1(5) and the latest patch) by entering the following MML command: 

/etc/init.d/CiscoMGC stop

Step 19 Install the Solaris 8 operating system and the necessary patches on Host B if you are upgrading from Cisco MGC 7.4(x). Install the necessary patches if you are upgrading from Cisco MGC 9.x. For installation procedures, refer to Chapter 2, "Sun Solaris 8 Operating System Installation."

Step 20 Restore the data files. Refer to the "Restoring Data Files" section and follow Step 1 through Step 5 to restore the data files.

Step 21 Install Cisco MGC 9.x software and the latest patch on Host B. For installation procedures, refer to the "Installing the Cisco MGC Software 9.2(x) and Higher Releases" section on page 3-3.

Step 22 Set the value of pom.dataSync=true. Use an editor such as vi to edit the file /opt/CiscoMGC/etc/XECfgParm.dat to set this value.

Step 23 Bring up Host B as standby.

Note Before starting the Cisco MGC software: If your configuration includes BAMS and you are upgrading to Cisco MGC 9.4(x), you must first re-apply the changes noted in Steps 4 and 5 in the section "Configuring the Cisco MGC for Using BAMS" of the BAMS User's Guide.

Step 24 Start the MGC software on Host B (which now has the Cisco 9.x software). Enter the following command: 

/etc/init.d/CiscoMGC start

Step 25 Wait for Host B to come up fully as standby host.

Step 26 If you are upgrading to Release 9.6(x) from Release 9.3(x), 9.4(x), or 9.5(x) and your Cisco PGW 2200 uses the MMDB, you must restart database replication between the active and standby hosts. Type the following command and press Enter: 

./setup_replication.sh

The upgrade from the Cisco MGC 7.4(x) and 9.x is now complete.

Downgrading the Cisco MGC Software Release

Two scenarios for downgrading to Release 7.4(x) or 9.x software release are detailed in this section:

•Scenario 1: Standby Host is Running Cisco MGC 7.4(x) or 9.x

•Scenario 2: Active and Standby Hosts are Running Cisco MGC 9.x or Later Software Release

Note Features in later software releases may not be supported if you are downgrading to an older release.

Scenario 1: Standby Host is Running Cisco MGC 7.4(x) or 9.x

When these two conditions apply, do the following procedures to downgrade from Cisco MGC 9.x:

•Host A (active Host) is running the latest version of Cisco MGC 9.x

•Host B (standby host) is running Cisco MGC 7.4(x) or 9.x and the latest patch

Step 1 Set the value of pom.dataSync=false. Use an editor such as vi to edit the /opt/CiscoMGC/etc/XECfgParm.dat file to set this value.

Step 2 Trigger switchover on Host A, the active Host, running Cisco MGC 9.x. Host B becomes active.

Step 3 Shut down Host A. Type the following command and press Enter: 

/opt/init.d/CiscoMGC stop

Step 4 On Host A, install the following:

a. Solaris 2.6 operating system and the necessary patches, if you are downgrading to Releases 7.4(x) or 9.1(5). Otherwise, proceed to Step 4b. For installation procedures, see Chapter 8, "Sun Solaris 2.6 Operating System Installation."

b. Software release originally installed on your system prior to the upgrade (either Cisco MGC 7.4(x) or 9.x.

For Cisco MGC installation procedures, see the following:

–For Cisco MGC 9.1(5), see Chapter 7, "Cisco MGC Software Release 9.1(5) Installation."

–For later Cisco MGC releases, see Chapter 3, "Cisco MGC Software Release 9 Installation."

–For Cisco MGC 7.(x), see the "Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide."

c. Latest patches (the same patch installed on Host B).

Step 5 Set the value of pom.dataSync=true. Use an editor such as vi to edit the file /opt/CiscoMGC/etc/XECfgParm.dat to set this value.

Step 6 On Host A, start the Cisco MGC software with the latest patches as standby host.

Step 7 Make sure the configuration is backed up.

Step 8 Make sure that replication of call states is occurring between Host B (the active host running Cisco MGC 7.4(x) or 9.x and the latest patch) and Host A (the standby host running Cisco MGC 7.4(x) or 9.x and the latest patches).

Type the following command and press Enter: 

rtrv-tc:all

This completes the downgrade procedure for Scenario 1: Standby Host is Running Cisco MGC 7.4(x) or 9.x. For assistance, call Cisco TAC.

Scenario 2: Active and Standby Hosts are Running Cisco MGC 9.x or Later Software Release

Caution All provisioning that is done after the upgrade will be lost because the system is using backup data.

To downgrade to Cisco MGC 7.4(x) or 9.1(5) when both the active and standby hosts are running Cisco MGC 9.3(2) or later software release:

Step 1 Shut down Host B (standby host).

Step 2 To restore data files, refer to the "Upgrading the Cisco MGC Software Release" section.

Step 3 If you are downgrading to Release 7.4(x) or 9.1(5), you must reinstall the Solaris 2.6 operating system and all of the patches that apply to it. Otherwise, proceed to Step 4. For installation procedures, refer to Chapter 8, "Sun Solaris 2.6 Operating System Installation."

Step 4 Create a CiscoMGC folder. Enter the following commands to create the CiscoMGC folder and extract data files: 

cd /opt

mkdir CiscoMGC

cd /opt/CiscoMGC

cp /tmp/saved/MGC.tar MGC.tar  

tar xvf MGC.tar

Step 5 On Host B, install Cisco MGC 7.4(x) or 9.x and the latest patch.

Step 6 On Host B, start the software release that was originally installed on your system prior to the upgrade (either Cisco MGC 7.4(x) or 9.x software) and the latest patch.

Step 7 Set the value of pom.dataSync=false. Use an editor such as vi to edit the file /opt/CiscoMGC/etc/XECfgParm.dat to set this value.

Step 8 Bring up Host B as standby.

Step 9 Make sure that the configuration is backed up.

Step 10 Make sure that replication of call states are occurring between Host A (the active host running the latest version of the Cisco MGC software) and Host B (the standby host running Cisco MGC 7.4(x) or 9.x and the latest patch).

On the standby Host B, type the following command and press Enter: 

rtrv-tc:all

Step 11 Trigger switchover on Host A. Enter the following command: 

sw-over::confirm

Host B should become active.

Step 12 Shut down Host A (now the standby host) and install the following:

a. Solaris 2.6 Operating system: If downgrading to Cisco MGC 7.4(x) or 9.1(5), see Chapter 8, "Sun Solaris 2.6 Operating System Installation."

b. Cisco MGC software release that was originally installed on your system prior to the upgrade—either Cisco MGC 9.x or 7.4(x).

For Cisco MGC installation procedures, see the following:

–For Cisco MGC 9.1(5), see Chapter 7, "Cisco MGC Software Release 9.1(5) Installation."

–For later Cisco MGC releases, see Chapter 3, "Cisco MGC Software Release 9 Installation."

–For Cisco MGC 7.(x), see the "Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide."

Step 13 Set the value of pom.dataSync=true. Use an editor such as vi to edit the file /opt/CiscoMGC/etc/XECfgParm.dat to set this value.

Step 14 Bring up Host A and ensure that call replication is taking place between Host A and Host B. Type the following command and press Enter: 

rtrv-tc:all

This completes the downgrade procedures for Scenario 2.

If Migration Fails

When upgrading the Cisco MGC software, you may encounter unique instances which result in migration failures. An unsuccessful migration is indicated by the following message in the log: 

Error migrating

If this occurs, you must install the latest patches then run config-lib, as shown in the following procedures.

Note If you are migrating to Cisco MGC 9.4(1) and the migration fails: The subroutine that adds the addition of the software packages exits and the last package is skipped after a migration failure. If this occurs, perform the following command on the file located in the APPLICATIONS directory:

cd APPLICATIONS
pkgadd -d CSC0gd004.pkg

Step 1 Download the latest Cisco MGC system and protocol patches.

Step 2 Run the config-lib script (this script resides in opt/CiscoMGC/local). Type the following command and press Enter: 

config-lib
