Upgrading a 4.1(3) cluster to version 7.1(3), using new servers and importing a DMA TAR file to restore db. I ran the Upgrade Assistant and it complained about memory (ok, I've got new servers), and the OS version on the old CallManager. It's OS version 2000.4.2 and the Upgrade Assistant wants version 2000.4.6.
My question is, does it matter? I'm just going to pull off the TAR file and use it during the new Communications Manager installation on the new appliance servers. Will DMA run ok on the current OS version?
I hate to have to upgrade the old servers, so if anyone has experience with this, please share.
