Upgrade CallManager-Does DMA Require Win2K OS Patch?

[mwheinz]

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.

Thanks!

DMA and Upgrade Assistant are 2 separate tools with independent purposes.  The Upgrade Assistant is used to determine if the hardware/software on your system is ready to be upgraded...in other words, it's a currency (that is, is everything current) and health check.

DMA is the tool used to prepare the export file for upgrade.  If you moving to Linux, I don't know of any interdependencies with OS and if you're using new servers for migration - then the hardware check doesn't really matter.

True, the hardware check is irrelevant, but does the Upgrade Assistant "know" that DMA requires a certain OS version in order to run on the current Windows CallManager?  That's the question.  Release notes for the DMA tool, nor the readme, indicate any required OS version to run this tool.

Thanks!

Sorry if my answer was vague, the Upgrade Assistant isn't checking anything as a pre-req for DMA.  It is checking readiness for an upgrade on the specific server it's being run on. 

I don't see any reason why you can't install DMA and run it on your server as-is.
