About Updating a System

In a Single-data Center (SDC) system, the data center must be put into Maintenance Mode.

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.

The complete update procedure, including backing up your virtual machines, might take up to an hour depending on:
  • System size

  • Database size

  • Speed of and load on the vCenter

Preparing to Update a Data Center

Procedure
    Step 1   Get the latest update file from Cisco at http:/​/​www.cisco.com/​cisco/​software/​navigator.html.

    The update package for your system includes an ISO image. You cannot skip some versions of the software. For example, you must install the Cisco WebEx Meetings Server version 1.1 (Build 1.1.1.9.A) or version 1.5 (Build 1.5.1.6.A) before applying 1.5 MR3. Check the release notes for the correct version to use.

    Step 2   Notify users that they cannot access the system for meetings during the update.
    Step 3   Notify other system administrators that they should not access any data center being updated during this procedure. If they do so, their changes are not saved and the results can be unpredictable.
    Step 4   Sign in to the Administration site.
    Step 5   Turn on Maintenance Mode. See Turning Maintenance Mode On or Off for Version 2.0 and Before.

    Unless you are expanding a system, we recommend that you take a snapshot of each virtual machine. (See Taking a Snapshot by using VMware vCenter.)

    Turning on Maintenance Mode on all active data centers shuts down conferencing activity and prevents users from signing in to the WebEx site, scheduling meetings, joining meetings, or playing meeting recordings. See About Maintenance Mode for information about which system tasks require Maintenance Mode to be turned on.

    Step 6   In the VMware vSphere client, select Power > Shut Down Guest on each of the virtual machines in the data center to be updated.

    For complete details on using vSphere, see the VMware ESXi and vCenter Server documentation.

    Step 7   Once the virtual machines are powered off, use VMware Data Recovery (or VMware vSphere Data Protection) to create a backup of each of the virtual machines in the data center.

    For more information, see Creating a Backup by using VMware vCenter. For complete details on this backup, see the VMware Data Recovery Administration Guide or the vSphere Data Protection Administration Guide.

    Note   

    You can also take a snapshot, but you should delete all snapshots in approximately 24 hours, or you might experience data performance issues. For more information, see Taking a Snapshot by using VMware vCenter.

    Caution   

    Create backups of all your virtual machines, because the update procedure makes changes to your existing virtual machines, and once the update procedure begins you will not be able to cancel the update.

    Step 8   In the VMware vSphere client, power on each of the virtual machines in your data center.
    Step 9   Log in to the Cisco WebEx Administration site, but do not turn off Maintenance Mode.
    Step 10   Select the System tab.
    Step 11   Select Upgrade.
    Step 12   Select Update to display the Update System page.

    What to Do Next

    Go to Connecting to an ISO Image from the CD/​DVD Drive for instructions on connecting the ISO image.

    Connecting to an ISO Image from the CD/DVD Drive

    For the fastest update, we recommend that you mount the ISO image in the vCenter datatstore. However, if you place it in a local disk accessible to the vSphere client, be sure the vSphere client has a hard-wired connection into your company Intranet (not over VPN).

    To place the ISO image in the vCenter datastore and connect to the CD/DVD, complete the following steps:

    Procedure
      Step 1   Get the desired ISO image from Cisco at http:/​/​www.cisco.com/​cisco/​software/​navigator.html.
      Step 2   Verify that you have the appropriate permissions.
      Step 3   Select the ESXi host for the Admin virtual machine of the data center to be updated. Select the Summary tab and double-click the datastore1 name under Storage.
      Step 4   On the Datastore and Datastore clusters window, select Browse this datastore.
      Step 5   Select the green up arrow icon (Upload file) and load the update ISO file.
      Step 6   Select the Admin virtual machine in the VMware vCenter inventory.
      Step 7   Select the CD/DVD icon for the Admin virtual machine.
      Step 8   Select CD/DVD drive 1 > Connect to ISO image on a local disk or on a datastore.
      Step 9   Confirm that the CD/DVD drive is connected.
      1. Right-click the Admin virtual machine name in the vCenter inventory and select Edit Settings....
      2. In the Hardware tab, select CD/DVD drive 1.
      3. If unchecked, check the Connected check box.
      4. Select OK.

      What to Do Next

      Update the data center by following the instructions at Updating a Data Center (version 2.0 and earlier).

      Update the data center with zero downtime by following the instructions at Updating a Multi-data Center System with Zero System Downtime.

      Updating a Data Center (version 2.0 and earlier)

      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   Select Continue on the Update System page in the Cisco WebEx Administration site.
        Step 3   Select I have connected to the ISO file and am ready to proceed.
        Step 4   Select Continue.
        Caution    Once you select Continue, you will not be able to stop the update procedure. If an issue arises during the update procedure, and it does not complete successfully, then you must use your backups to restore the system.

        The update procedure may take up to an hour. Do not close the browser window, as you will be unable to return to this page.

        Once the update completes, a new page is displayed, confirming the success of the update.

        Note   

        There is an intermittent issue where the update completes successfully, but you do not see text stating System Updated and a Restart button. If the update does not complete, and it has been longer than an hour, then you can attempt to turn off Maintenance Mode. If you cannot turn off Maintenance Mode, then the update is still in progress. Once the update is finished, reboot all virtual machines from vCenter. Wait for the virtual machines to come online and verify the system version on the dashboard.

        Step 5   Select Restart to restart the system.

        This page has a default timeout value of 90 minutes. Be sure you restart the system within this time period, or change the default timeout to a longer period of time.

        Step 6   Select Restart.

        The Cisco WebEx Administration site sign on page is displayed.

        Step 7   Sign in to Cisco WebEx Administration. The updated version is displayed on the dashboard.
        Step 8   Check the release notes for this update, and determine whether any post-update tasks are required. If additional tasks are required, complete them before you take the system out of maintenance mode.
        Step 9   Turn off Maintenance Mode. See Turning Maintenance Mode On or Off for Version 2.0 and Before.

        When you turn off Maintenance Mode, the system determines if a restart (takes approximately 3 - 5 minutes) or a reboot (takes approximately 30 minutes) is required and displays the appropriate message.

        Meeting service for users on this data center is restored.
        Step 10   Test the system. You can accomplish these tests and validate your system by using two diagnostic tools provided on the support pages for this product, the Meetings Test and the System Resources test.
        • Add, edit, activate, an deactivate users.

        • Schedule and hold a meeting.

        • Reschedule an existing meeting.

        • Delete a series of meetings or a future meeting.

        • Open a meeting attachment.

        • Play a meeting recording.

        We recommend that when you are satisfied with the operation, that you remove the backups.
