Polycom 3725-76302-001O manual To roll back an upgrade, restoring the previous version

aIn a two-server cluster, verify on the Dashboard that both servers are up and the private network connection is operating properly.

bGo to Maintenance > Software Upgrade and check the Operation History table.

cIf the upgrade requires a new license activation key code or codes, obtain and install them as described in Add Licenses on page 82.

12If this cluster is part of a supercluster, do the following:

a Go to Network > RealPresence DMAs, and rejoin this cluster to the supercluster. See Supercluster Procedures on page 230.

Caution: Rejoin the Correct Cluster

Be sure you select the cluster you just upgraded (the one you’re logged into) and join it to another cluster, not the other way around.

bGo to Network > Site Topology > Territories and reassign territory responsibilities back to this cluster. Or, if previously integrated with a Polycom RealPresence Resource Manager or CMA system, go to Admin > Integrations > Resource Management System. and reestablish the integration.

Integration with a resource management system imports the site topology data, including territory assignments, from that system.

13Call Polycom Global Services if:

After waiting significantly longer than the estimated install time, you’re still unable to log back in.

You can log in, but the Dashboard shows only one server for a two-server cluster.

The package version numbers on the two servers are not the same.

14For a supercluster, repeat the above procedure for each additional cluster.

To roll back an upgrade, restoring the previous version

1Go to Maintenance > Software Upgrade.

2Verify that you want to downgrade the system to the rollback version shown and that you’re prepared for a system restart, if required.

Most rollbacks will require a restart.

3If this cluster is part of a supercluster and you’re rolling back after rejoining the supercluster, do the following:

a If integrated with a Polycom RealPresence Resource Manager or CMA system, go to Admin > Integrations > Resource Management System. and terminate the integration.

b Go to Network > Site Topology > Territories and reassign the cluster’s territory responsibilities. Wait a few minutes and verify on another cluster that the change has been replicated.

c Go to Network > RealPresence DMAs and take it out of service (or busy it out and wait for all calls to end).

dSelect this cluster and click to remove the cluster, click

Remove from Supercluster. When asked to confirm that you want Yes.

The cluster is removed from the supercluster. A dialog box informs you when the process is complete. Then it logs you out and restarts.

eClick OK to log out immediately, or simply wait.
