Upgrade CUCM 9.1 to 10.5

[Ioannis John Xiouras]

Hello,

I am looking for the recommended upgrade path for CUCM 9.1 to 10.5. The installation consists of a publisher and a subscriber (different locations) and we are using UCS C240 servers. Which procedure would minimize the down time? Can we create new VMs for publisher and subscriber with ver. 10.5 and restore the database from 9.1.1? I appreciate any input or opinion.

Thanks.

John

And just for clarification, NO, you cannot restore a DRS backup on any other version, that DRS backup needs to be restored on the exact same version from which it was taken.

Jaime is correct.

Caution from one of many Cisco DRS docs expressing the same message:

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 8.6.1.20000-1 to version 8.6.2.20000-2, or from version 8.6.2.20000-2 to 8.6.2.21900-5.
