I'm in the initial stages of planning a new CUCM 6.x cluster to replace our current production cluster at 4.1(3). This is centralized call processing for roughly 10 sites. We are going to create a new cluster and move sites in one-by-one.
When I actually start the first server build, is it acceptible to have the server in the same network as the production cluster? I don't want anything in the initial build(s) to impact the production environment.
Any other considerations or gotchas I might run into?
