Roll Back Cluster to a Pre-8.0 Release Before you roll back a cluster to a pre-8.0 release of Unified Communications Manager, you must prepare the cluster for rollback using the Prepare Cluster for Rollback to pre-8.0 enterprise parameter. To prepare the cluster for rollback, follow this procedure on each server in the cluster. Procedure Step 1 From Unified Communications Manager, choose System > Enterprise Parameters Configuration. The Enterprise Parameters Configuration window displays. Set the Prepare Cluster for Rollback to pre-8.0 enterprise parameter to True. Note Enable this parameter only if you are preparing to rollback your cluster to a pre-8.0 release of Unified Communications Manager. Phone services that use https (for example, extension mobility) will not work while this parameter is enabled. However, users will be able to continue making and receiving basic phone calls while this parameter is enabled. Step 2 Wait ten minutes for the Cisco IP Phones to automatically restart and register with Unified Communications Manager. Step 3 Revert each server in the cluster to the previous release. For more information about reverting a cluster to a previous version, see Administration Guide for Cisco Unified Communications Manager . Step 4 Wait until the cluster finishes switching to the previous version. Step 5 If you are running one of the following releases in mixed mode, you must run the CTL client: • Unified Communications Manager Release 7.1(2) • All regular releases of 7.1(2) • All ES releases of 712 prior to 007.001(002.32016.001) • Unified Communications Manager Release 7.1(3) Security Guide for Cisco Unified Communications Manager, Release 15 and SUs 31 An Introduction to Unified CM Security Obtain Cisco Unified IP Phone Support List
