There is no downgrade in CUCM.

If you had 7.1(3) and then upgraded to 7.1(5) what you can do is a rollback to the old version.

You'll go back to the exact same point where you upgraded, any config changes done after the partitions were switched won't be there.

If you have a fresh 7.1(5) install then you need the media to do a fresh 7.1(3) install.

Hi Java,

is it possible to use cucm 7.1.5 backup to build new 7.1.3 server?.

Hi Thomas,

Sadly not

In the DRS restore procedure the versions must match exactly. Here is an

excerpt from the DRS Guide;

Caution Before you restore Cisco Unified Communications Manager, ensure that the Cisco Unified Communications Manager version that is installed on the server matches the version of the backup file that you want to restore. The Disaster Recovery System supports only matching versions of Cisco Unified Communications Manager for restore. For example, the Disaster Recovery System does not allow a restore from version 6.1.(1).1000-1 to version 6.1(2).1000-1, or from version 6.1.(2).1000-1 to version 6.1(2).1000-2

Note The Disaster Recovery System does not migrate data from Windows to Linux or from Linux to Linux. A restore must run on the same product version as the backup. For information on data migration from a Windows-based platform to a Linux-based platform,
