UCS Server upgrade

[Mark Verwey]

I have a new task to upgrade my current UCS servers that host CUCM, CUC, UCCX, and Presence to the newest UCS servers because they have reached EOL/EOS with Cisco TAC.  I understand that I will have to get with the licensing team once I am done so that I can rehost the licenses for all servers.  I'm also not that worried about the subscribers as I can just install them fresh and have them replicate from the Publisher.  However, I don't want this evolution to take a month to complete (a different story different time).  If I do a DR backup off the old server then restore to the new server how will I handle the change of the MAC on the new publishers of each of these servers. Also, because of bad past experience attempting to use DR backups to restore from I don't really have a good feeling this will be successful.  Can anyone offer a better solution?

Shutdown the VMs and move them to the new host, or if you have vCenter, shut them down, and vMotion them.

Don't have vCenter and have never moved a server only made a snap shot of a server in case I screwed something up.  I'm assuming there is a way to make a copy on a VM without vCenter, move it off that host and onto another one.  Is this what you are saying?

[Jaime Valencia]

yes

thanks for the quick response, one more question.  What happens to the change in the MAC's?  The license MAC isn't a big deal I don't think but all the other MAC's change as well don't they?
