Migrating to Cisco MGC Software Release 9.3(1)

This chapter describes procedures for migrating to the Cisco MGC 9.3(1) software from Cisco MGC software release 9.2(2).

Before you Begin

Caution Before starting the upgrade, verify the existing system status and make sure there are no major alarms.

To ensure a smooth migration, we recommend the following steps:

1. Start the procedure on the standby box (Host B).

2. After Host B is migrated to Release 9.3(1), shut down the active box (Host A) before starting Cisco MGC 9.3(1) on Host B. A brief service interruption will occur while both systems are out of service.

3. After starting Cisco MGC 9.3(1) on Host B, perform acceptance testing to verify that the migration is successful.

Note Do not make any provisioning changes during the migration and verification period.

If any part of the testing fails, try to resolve the problems within a reasonable period of time. If the problem cannot be resolved, perform backout procedures.

4. When migration of both Host A and Host B to Release 9.3(1) is complete, perform failover testing to verify redundancy.

Conditions for Migration

Your hardware and software environment must meet the following conditions before you can use the procedures provided below to migrate your software to the Cisco MGC software release 9.3(1):

1. Your system must have at least 2 disks.

2. The disks in the system must be at least 18 GB in size.

3. You (or the person doing the upgrade) must be an experienced Solaris system administrator. You must be familiar with system administration tasks such as mounting file systems and running tar to save and restore files.

Quick Guide to Migration

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

The following table provides a quick guide to migrating to Cisco MGC software release 9.31). For details, refer to the page numbers located on the right-hande column of the table.

Migrating Host B (Standby Box)

Verify the Existing Network Status

From Host B (standby box):

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

mml>rtv-alms

Step 2 If alarms are found, resolve all before proceeding with migration.

Proceed to the following procedure, "Back Up the PGW Configuration on Host A".

Back Up the PGW Configuration on Host A

To back up the PGW configuration on Host A:

Step 1 Log in as mgcusr.

Step 2 Enter the following command: 

mml>prov-exp:all:dirname="922-backup"

Step 3 Go to /opt/CiscoMGC/etc. Enter the following command: 

% cd /opt/CiscoMGC/etc

Step 4 Record the active link. Enter the following command: 

% ls -l

Step 5 Create an mgc-922-backup directory under /tmp. Enter the following command: 

% mkdir /tmp/mgc-922-backup

Step 6 Go to /opt/CiscoMGC/local. Enter the following command: 

% cd /opt/CiscoMGC/local

Step 7 Back up the PGW configuration on Host A. Enter the following commands: 

% mgcbackup -d /tmp/mgc-922-backup

% cd /tmp/mgc-922-backup

Step 8 Using FTP, transfer the backup configuration files to a remote server and a remote storage location such as a laptop computer.

Caution These files must now be moved to a remote server and remote storage location so they can be recovered if necessary. You are responsible for providing the mechanism and storage location.

Proceed to back up Host B.

Back Up the PGW Configuration on Host B

To back up Host B's PGW configuration:

Step 1 Log in as mgcusr.

Step 2 Create an mgc-922-backup directory under /tmp. Enter the following command: 

% mkdir /tmp/mgc-922-backup

Step 3 Enter the following command: 

% mgcbackup -d /tmp/mgc-922-backup

Step 4 Go to /opt/CiscoMGC/etc. Enter the following command: 

% cd /opt/CiscoMGC/etc

Step 5 Copy the XECfgParm.dat file. Enter the following command: 

% cp XECfgParm.dat/tmp/922-backup/XECfgParm.dat.922

Step 6 Verify whether both the backup and XECfgParm.dat.922 files are present, indicating that the backup is successful. Enter the following command: 

% cd /tmp/922-backup

Step 7 Using FTP, transfer the backup and XECfgParm.dat.922 files to a remote server and a remote storage location such as a laptop computer.

Caution These files must now be moved to a remote server and remote storage location so they can be recovered if necessary. You are responsible for providing the mechanism and storage location.

Proceed to the following section, "Remove Cisco MGC 9.2(2) from Host B".

Remove Cisco MGC 9.2(2) from Host B
