An upgrade was done a few months ago to Unity Connection 8.5.1 restricted to 8.6.2. 8.5.1 is still in the inactive partition. What are my options to go back to restricted version.
I was told that I could revert back to 8.5.1 but all changes made after the upgrade to 8.6.2 unrestricted will be lost. I was also told I could do a back up using COBRAS then restore it to a fresh install of 8.6.2 restricted.
If anyone has encountered this scenario or has any ideas please share.
As said by David , u need to have exactly the same version.
Before you restore Cisco Unity Connection, ensure that the Cisco Unity Connection 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 Unity Connection 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.
The backup and Restore wont work like David said .. but COBRAS should... and you should be able to restore most of the imp items .. and also go from any to any version .. Just put on a new VM and move licenses if everythign is working.
