I have a strange requirement from my customer. He wants to have his CCM installed in such a way that he has one version of the software installed on one partition on the disk, but when he makes an upgrade, that the upgrade is done on other partition, leaving the first one intact (for backup I suppose??). Can anything like this be done? Only thing that crosses my mind is to pull out one of the mirrored disks and perform upgrade on the other one, leaving the first one as backup. His requirement seems absurd, but I have to respond on this as either being possible or not.
Thanks for any suggestions...
use a linux appliance version 5.X or later to do that, the system itself does that without even asking you if you want it or not
you will have active and inactive partition and you can rollback to previous version if needed.
really CUCM 101 question
