we work on an upgrade from our callmanager cluster from 3.3(4) to 4.2(3). To test the upgrade we plan to set up a preproduction. The preproduction has its own subnet and a different naming convetion. It is possible to import the callmanager backup from the running publisher to the preprod publisher? (they have different names cmp1 / cmt1 and different IPs 172.29.xx.xx / 10.29.xx.xx)
Or is it possible to take a disk out of the RAID1 of the publisher, insert it to the preprod publisher and change the Name and the IP in the CallManger config?
Thank for a feedback
