Upgrading Windows Server from Standard to Enterprise

[nanobaka]

Hi All,

We have a development server that is running Windows Server 2003 R2 Standard 64bit, with 18gb of RAM. We have TM1 9.5.2 and Cognos BI 10.1 installed. We upgraded the RAM from 18gb to 64gb but since Windows Server is Standard Edition, it can only use 32gb. The recommendation is to upgrade from Standard to Enterprise Edition. Does anyone know how upgrading (not reinstalling from scratch) Windows Server this way will affect TM1 and BI installation? We asked IBM about it and the engineer who replied said from his experience it *should* be OK, but he recommends a full backup before proceeding. (The question itself is outside their typical support/QA experience, so they do not know that much about it too.)

Did anyone here ever done this before?

Thanks,
wy

When doing something like this I have only ever done a backup, complete re-install of windows and restore of both TM1 and BI. I've never tried doing an upgrade. Based on what I have heard of other peoples experience of upgrading MS OS's I would avoid it. It may work but overhead generated by the upgrade could effect performance going forward,

Jim.
