CUCM 7.1 to 8.6 Upgrade- when to add License?

Hi All,

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.

Thanks,

Hamed

License on UCS is different, if you already have it it does not matter when you install it before or after the restore.
