Before You Begin
Before you begin the installation, review the following information:
-
Make sure that the subscriber nodes that you are installing can connect to the publisher node server during the installation.
-
Make sure that all Cisco Unified Communications Manager servers in a cluster have the same software version. Make sure that all IM and Presence servers in a cluster have the same version of the released software. The only exception is during a cluster software upgrade, during which a temporary mismatch is allowed. If you are installing IM and Presence nodes, Cisco Unified Communications Manager and IM and Presence Service software versions must have the same major and minor release number.
-
Do not attempt to perform any configuration tasks during the installation.
-
Be aware that directory names and filenames that you enter while you are running the installation program are case-sensitive.
-
For a short period of time after you install Cisco Unified Communications Manager or switch over after upgrading to a different product version, settings changes made by phone users might get reset. Examples of phone user settings includes call forwarding and message waiting indication light settings. This can occur because Cisco Unified Communications Manager synchronizes the database after an installation or upgrade, which can overwrite phone user settings changes.
