I am planning on upgrading/installing from an existing 3.1(2c) CM to a 3.3(2). I know this upgrade is not on the compatibility matrix from Cisco but I also do not have any additional applications installed on the 3.1(2c) server (CRS, CRA, ICM, CCC, ....). Without using these apps I'm assuming the upgrade should work fine??
The other question is what instructions do I follow, the upgrade or the new installation instructions?? I plan on using the latest STIbackup from the 3.3(2) CD's to backup the existing CM and then rebuilding the machine from scratch. Prior to this I will be pulling the HD and replacing it for extra protection.
What are the consequences from upgrading from 3.1(2c) to 3.3(2). From my understanding it should just be restoring the CM info. I spoke with another TAC engineer and they said it should be ok to do this as long as I am not using other CM applications. If this is strictly requiered to upgrade first to 3.1(4b) then I will definitely do that. Is that upgrade available from the Cisco website?
