Hello,
I am looking for some advice on an upgrade. We are currently running the following versions. I was originally planning to upgrade CUCM and update the other applications in a staged order. I then realized that the newest version of CUCM is not compatible with any of our current application version. I have never upgraded a UC environment so am looking for recommendations. Would it be better to upgrade CUCM to 11.5 so I can wait on the other upgrades and then bring them up to 11.5 before going to 12? Currently we have active partition 10.5.2.x and inactive 9.x. Would it be better to create new VM's and do a DRS backup/restore or just in place direct upgrades?
The upgrade seemed straight forward at first however, the more I research the more intimidating it is.
