Upgrading Global Mailbox

You can upgrade Global Mailbox without changing the values that are set in the previous versions.

Before you begin

Important: Global Mailbox per-requisite services must be started at least once before you upgrade it.

Complete the following tasks:

  1. Ensure that you back up the following components on every node:
    • Sterling B2B Integrator and the database
    • Cassandra
    • ZooKeeper
      Important: You must manually back up watchdog.properties file to retain all the changes.
    Important: If for some reason the update is interrupted or stopped midway, you must manually revert the changes by using the backed up files, and then restart the update installation.
  2. Ensure that you upgrade WebSphere® MQ to 9.0.0.4.

    For more information, see Migrating IBM MQ.

  3. Ensure you have stopped the following components on every node:
    • Cassandra
    • ZooKeeper
    • Global Mailbox
    • Sterling B2B Integrator
      • To stop a single node, go to the \<install_dir>\install\bin (Windows) or /<install_dir>/install/bin (UNIX or Linux) directory, open a command prompt and enter the StopWindowsService.cmd (Windows) or ./hardstop.sh (UNIX or Linux) command. Wait until the perimeter server of the node is completely down before installing the fix pack.
      • To stop the cluster, open the Sterling B2B Integrator user interface (dashboard), and complete the following tasks:
        1. From the Administration menu, select Operations > System > Troubleshooting.
        2. Click Stop the System.
Important: IBM JDK 8 should be installed before upgrading Cassandra nodes to the latest version. The installer confirms the version of JDK 8 at the path provided during installation. An error message is displayed if the path is not to the correct version of Java.
