Hope find someone to help me, I have CUCM 7.1 cluster with One Pub and two Subs all on discontinued Servers, I need to upgrade to 8.6 in UCS.
I already Upgraded 7.1 to 8.6( Just Publisher) and then did DRS.now I need to restore it to the new CUCM 8.6 on UCS.
Should I import license on the new 8.6 and then restore backup or I should first restore backup and then add license? I have found some people here saying we should Restore the backup then add license.
Also if you have a CUCM cluster with DEMO license and you restore backup containing 10000 DLUs, What Would happen?
I just did upgrade on Publisher, then Get the DRS but cisco saying we should upgrade all Nodes and then get DRS? Why is that? I am not using the discontinued MCS server why I should upgrade all nodes to get the DRS.
My Last question: how I can get the backup from the license currently on the cucm, I lost the original License and now I want to get the backup of it.
