Basic Upgrade Procedures

Caution: Upgrade Considerations

Always check the upgrade version release notes before installing an upgrade.

The upgrade installation process automatically creates a backup, which enables you to roll back an upgrade (restore the previous version) if necessary. As a precaution, however, we recommend that you download a recent backup file before you begin to install an upgrade. See Backing Up and Restoring on page 374.

You can roll back only the last applied upgrade. Rolling back an upgrade restores the database to its state prior to the upgrade, so data may be lost.

The procedure below is for:

•Installing any software upgrade on a single-server or two-server system that’s not part of a supercluster.

•Installing a patch (supercluster-compatible software upgrade) on a cluster that’s part of a supercluster. In that case, you repeat the procedure on each cluster.

To apply a major or minor software upgrade (not supercluster-compatible) to a superclustered system, see Incompatible Software Version Supercluster Upgrades on page 386.

Note: Upgrade Tips

To minimize the time required for an upgrade:

•If the upgrade requires a new license, obtain the license activation key(s) ahead of time.

•Download a recent backup and upload the upgrade package file (the first five steps below) ahead of time. For a supercluster, do this on each cluster.

•Perform the remainder of the procedure during a maintenance window when there are no calls or conferences so that you can immediately take the cluster out of service instead of having to wait for all activity to end.

Using a maintenance window with no calls on the system also eliminates any concerns about whether the remaining clusters of a supercluster have sufficient capacity to handle the load of the cluster being upgraded.

Note: Redirecting Endpoints to a Different Call Server

To successfully redirect certain older or third-party endpoints to a different Call Server in the supercluster, one of the following may be necessary:

•Managed endpoints may be re-provisioned by the Polycom RealPresence Resource Manager system, CMA system, or third-party endpoint management system responsible for them.

Unmanaged endpoints may be manually reconfigured and if necessary restarted (in some cases, restarting an endpoint may be sufficient).
