Version Requirements
All servers in a cluster must run the same release of Unified Communications Manager. The only exception is during a cluster software upgrade, during which a temporary mismatch is allowed.
If you are installing IM and Presence nodes, the software version of the first IM and Presence node (the IM and Presence database publisher node) must match the first three numbers of the software version installed on the Unified Communications Manager publisher node. For example, IM and Presence Service software version 10.0.1.10000-1 is compatible with Unified Communications Manager software version 10.0.1.30000-2. Refer to the following table for sample Unified Communications Manager versions and IM and Presence Service versions that are compatible. The bolded numbers must match.
Sample Unified Communications Manager Version |
Example of Compatible IM and Presence Service Version |
---|---|
10.0.1.30000-2 |
10.0.1.10000-1 |
10.5.1.10000-7 |
10.5.1.10000-9 |
10.5.2.10000-5 |
10.5.2.10000-9 |
After you install the first IM and Presence node, the software version of any IM and Presence subscriber nodes that you install must match all five version numbers of the first IM and Presence node. For example, if the IM and Presence database publisher node is at version 10.0.1.10000-1, then all IM and Presence subscriber nodes must also be 10.0.1.10000-1.
