Upgrading the System

Upgrading the System

Preparing to Upgrade a Data Center

Your system can be upgraded by redeploying it with an upgraded OVA (Virtual Server Template) file. The upgrade procedure creates a parallel system and the data from the original system is transferred to the upgraded system as part of the upgrade process. If the upgraded system fails testing, you can restart the original system to restore service, fix any errors, and redeploy an upgraded system.

An upgrade is defined as a replacement of the system to deploy major modifications that we made to the system. For example replacing a system currently running version 1.5 to run version 2.0 that includes support for a new operating system. An update is defined as overwriting an existing (original) system to take advantage of modifications that we made to improve the system. An expand is defined as enlarging an existing system, but not changing the application version. For example, you might update a system from version 1.5 to 1.5MR, upgrade a system from 1.5 to 2.0, or expand a system from 800 users to 2000 users. In all cases, the processes include transferring all of the data from the original system to the updated, upgraded, or expanded system.

Use the following table to determine if you should perform a system upgrade or update on a data center to run a specific release of Cisco WebEx Meetings Server.
Note   

When data centers are deployed, one of the choices is between Audio Encrypted -AE or Audio Unencrypted -AU. Once deployed, systems cannot be converted from one type to the other, nor can data archived or backed up from one type of system be uploaded to the other type of system. When updating or upgrading a system, the audio encryption status cannot be changed. The only way to change a system from one type of audio encryption to another is to deploy a new system.

The system can be upgraded automatically or manually. We recommend that you upgrade the system by using the automatic process.

When upgrading:


Note


We refer to the system in place before initiating the upgrade as the original system. The system in place following upgrade is referred to as the upgraded system.

Before You Begin an Automatic or Manual Upgrade

Before upgrading a system automatically or manually, the following issues should be addressed:

Upgrading the System Automatically

This procedure lists the high-level tasks needed to complete an automatic upgrade. It includes links to sections of the Cisco WebEx Meetings Server Administration Guide (at http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-and-configuration-guides-list.html) that provide the detailed steps necessary to complete each task.

Before You Begin

Before upgrading a system by using the automatic upgrade process:

  • Notify other system administrators that they should not access or make changes to the original system during the upgrade, as their changes might yield unpredictable results.

  • Notify other system administrators that they should not access or make changes to the original system during the upgrade, as their changes might yield unpredictable results.

  • Provide and configure one additional IP address and hostname that will be used temporarily for the administration virtual machine on the upgraded system. This can be any available IP address in the VLAN. The hostname can be anything you want, as this IP address and hostname will be released at the end of the upgrade process.

    The original system and the upgraded system are both powered up during this process. The temporary IP address and hostname prevents IP conflicts during this part of the procedure. After the data is transferred from the original system to the modified system, the original system is powered down. At the end of the process, the modified system is taken out of maintenance mode and re-boots.

    During the reboot, the temporary IP address and hostname are released and the modified system uses the original administration virtual machine IP address and hostname.

    If there is a firewall between the administration virtual machines and the IRP virtual machines, the temporary IP address must be allowed through the firewall.

  • Do not manually power on or shut down either system.

  • Verify that vSwitch is not used on ESXi hosts as a distributed switch. Automatic processes do not support vSwitch Distributed Switch on CWMS ESXi hosts. Change to a standard switch or use a manual process. (See Upgrading the System Manually, Updating Data Centers Version 2.5 and Higher With System Downtime, or Expanding the System Size.)

Procedure
    Step 1   Clear your browser cache.

    Static resources are cached to enhance the performance of web pages; however, the data cached might be incorrect. Therefore, we recommend that you clear your browser cache.

    Step 2   Go to the license manager on the original system and generate a license request by selecting System > View more > Manage Licenses. License manager opens in a new tab.
    Step 3   Select Generate License Request. A pop-up appears with the license request text. Copy the text and save the license request in a convenient location as it might be necessary to use the manual re-host procedure to reclaim your licenses. This information can also help Cisco to find your licenses. (See Fulfilling Licenses by using the License Manager.)
    Step 4   Using the vSphere client, deploy the Admin virtual machine (by using the temporary IP address) for the upgraded system by selecting the configuration with the Auto-upgrade suffix, for example 250 Users Admin Auto-upgrade. Use the same host as the original system Admin virtual machine.
    Step 5   Verify that the Upgrade Administration virtual machine can reach the original system disks.

    The Administration virtual machines are on the same ESXi host and have access to the same data stores, therefore they should be able to view both sets of disks. The datastore used by the Administration virtual machine datastore (vmdk) files should be visible through the vCenter (by using the same vCenter credentials that the automatic upgrade process uses).

    Step 6   Power on the Administration virtual machine for the upgraded system and write down the deployment URL displayed on the virtual machine console.
    Step 7   Enter the deployment URL into a web browser URL field.
    Step 8   Enter the Administration and vCenter URLs and credentials, so we can deploy the virtual machines for you. (See Providing VMware vCenter Credentials.)
    Step 9   To deploy any additional virtual machines, select Continue.

    Until you begin the setup of the upgraded system and the original system is placed in maintenance mode, users can hold meetings, but administrators should not modify the original system virtual machines.

    Step 10   Note the names of the automatically-created virtual machines listed in vCenter.

    The format for virtual machine names is CWMS_hostname_MMDDHHmm where mm=minute

    When the upgrade is complete, the virtual machines do not display. To find the virtual machines that were created as part of the CWMS upgrade, you can search based on this format.

    The progress of the upgrade is displayed on the deployment URL of the upgraded system and on the VMware console connected to the primary system Admin virtual machine. The VMware console provides the deployment URL to use in case the browser window inadvertently closes during the upgrade process.

    Step 11   To automatically put the system in maintenance mode and begin the setup of the upgraded system, select Continue. A message displays when Maintenance Mode is enabled, which might take up to 30 minutes.
    Step 12   To launch the upgraded Cisco WebEx Administration site, select Sign In to Administration Site and sign in.
    Step 13   Wait for the system to come to a good state, then turn off maintenance mode on the upgraded system and select Continue.

    It might take a few minutes for the meeting service to become available. Your system is ready for users to start meetings when all the virtual machines listed on the System Properties page display a status of Good (green). See Turning Maintenance Mode On or Off for Version 2.0 and Before for more information.

    The system reboots.
    Step 14   Test the upgraded system. (See About System Testing.)

    When your upgraded system is running satisfactorily, you can delete your original system to free the original system resources. Keep the upgraded system running while deleting the original system to prevent the accidental removal of the Hard disk 4 base VMDK file that might be accessed by the upgraded system.

    If the upgrade is unsuccessful, power off the upgraded system, power on the original system, and contact Cisco TAC.

    Step 15   Re-host and update the license version as appropriate for the upgraded system. (See About Host Licenses and Re-hosting Licenses after a Major System Modification).

    If the previously deployed Cisco WebEx Meetings Application or Productivity Tools are different versions or build numbers from a newly deployed version of the application and the upgrade is not blocked, you are notified by an upgrade warning dialog box. It might be necessary to push the Cisco WebEx Meetings Application or Productivity Tools to the users. See the Cisco WebEx Meetings Application and Productivity Tools Compatibility Matrix section of the Cisco WebEx Meetings Server Planning Guide, found at http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-and-configuration-guides-list.html.

    Within 180 days or less the license-free grace period shall expire. If the original system had valid licenses, those licenses must be re-hosted in 180 days or less. If the original system was operating in the license-free grace period, the remaining unexpired days are transferred to the upgraded system.

    What to Do Next

    If the previously deployed Cisco WebEx Meetings Application or Productivity Tools are different versions or build numbers from a newly deployed version of the application and the upgrade is not blocked, you are notified by an upgrade warning dialog box. It might be necessary to push the Cisco WebEx Meetings Application or Productivity Tools to the users. See the Cisco WebEx Meetings Application and Productivity Tools Compatibility Matrix section of the Cisco WebEx Meetings Server Planning Guide and System Requirements, found at http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-and-configuration-guides-list.html.

    Upgrading the System Manually

    This procedure lists the high-level tasks needed to complete an manual upgrade. It includes links to sections of the Cisco WebEx Meetings Server Administration Guide (at http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-and-configuration-guides-list.html) that provide the detailed steps necessary to complete each task.

    Before You Begin

    Verify that the upgraded system can access the disks for the original system Admin virtual machine. (Hard disk 4 will be copied from the original system to the upgraded system.)

    Do not power on and run both systems at the same time, because the hostnames and IP addresses from the original virtual machines are used in the upgraded system.

    Procedure
      Step 1   Clear your browser cache.

      Static resources are cached to enhance the performance of web pages; however, the data cached might be incorrect. Therefore, we recommend that you clear your browser cache.

      Step 2   Go to the license manager on the original system and generate a license request by selecting System > View more > Manage Licenses. License manager opens in a new tab.
      Step 3   Select Generate License Request. A pop-up appears with the license request text. Copy the text and save the license request in a convenient location as it might be necessary to use the manual re-host procedure to reclaim your licenses. This information can also help Cisco to find your licenses. (See Fulfilling Licenses by using the License Manager.)
      Step 4   Login to the Administration site of the original system.
      Step 5   Go to the System tab and select Upgrade.
      Step 6   Select Major Upgrade.
      Step 7   Select Continue to archive the original system data and put the system into maintenance mode.
      Step 8   Using the VMware vSphere client, select Power > Shut Down Guest on the virtual machines for the original system.
      Step 9   Deploy all of the upgraded system virtual machines, including the high availability (HA) and Internet Reverse Proxy (IRP) virtual machines.

      During deployment there is an option to Power on VM after deployment. Verify that this is not checked or that the VMs have been started manually before the next step is complete; otherwise, it will cause the VMs to deploy as a new system and create a new deployment instead of migrating the data. If the VMs are powered on, they must be deleted and redeployed before proceeding.

      Step 10   Copy the data from your original system to the Admin virtual machine for the upgraded system. (See Attaching an Existing VMDK File to a New Virtual Machine.)
      Step 11   Power on the upgraded Admin virtual machine and write down the deployment URL displayed on the virtual machine console. (See Configuring a High Availability System.)

      If the system will include HA, do not setup the HA virtual machines from HA Admin Deployment; allow the upgrade script to discover the HA virtual machines.

      Step 12   Power on the other upgraded virtual machines.
      Step 13   Enter the deployment URL into a web browser.
      Step 14   Select Continue to launch the system setup.

      The progress of the upgrade is displayed on the deployment URL of the upgraded system and on the VMware console connected to the primary system Admin virtual machine.

      The VMware console provides the deployment URL to use in case the browser window inadvertently closes during the upgrade process.

      Step 15   Wait for the system to come to a good state, then turn off maintenance mode and select Continue.

      It might take a few minutes for the meeting service to become available. Your system is ready for users to start meetings when all the virtual machines listed on the System Properties page display a status of Good (green). See Turning Maintenance Mode On or Off for Version 2.0 and Before for more information.

      Step 16   Test the upgraded system. (See About System Testing.)

      When your upgraded system is running satisfactorily, you can delete your original system to free the original system resources. Keep the upgraded system running while deleting the original system to prevent the accidental removal of the Hard disk 4 base VMDK file that might be accessed by the upgraded system.

      If the upgrade is unsuccessful, power off the upgraded system, power on the original system, and contact Cisco TAC.

      Step 17   Re-host and update the license version as appropriate for the upgraded system. (See About Host Licenses and Re-hosting Licenses after a Major System Modification).

      If the previously deployed Cisco WebEx Meetings Application or Productivity Tools are different versions or build numbers from a newly deployed version of the application and the upgrade is not blocked, you are notified by an upgrade warning dialog box. It might be necessary to push the Cisco WebEx Meetings Application or Productivity Tools to the users. See the Cisco WebEx Meetings Application and Productivity Tools Compatibility Matrix section of the Cisco WebEx Meetings Server Planning Guide, found at http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-and-configuration-guides-list.html.

      Within 180 days or less the license-free grace period shall expire. If the original system had valid licenses, those licenses must be re-hosted in 180 days or less. If the original system was operating in the license-free grace period, the remaining unexpired days are transferred to the upgraded system.
