Upgrading 32 bit DCs to 2008 R2?

Hello experts,

I have a question and I think I know the answer but wanted to make sure.

We currently have a domain that is at a Forest Level of 2003 but all domain controllers are 2008 32 bit.  (ugh).

I need  to upgrade the domain to 2008 R2.  I cannot prep the forest from a 32 bit domain controller and need to do it from a DC.  We do not have a 64bit DC.  Do I need to add one just to prep the forest?

My plan was to prep the forest, I have 3 R2 servers I want to upgrade to DC's and transfer services and roles over but I'm stuck at the very beginning and glad I am finding out now in my test lab.

Thank you,

Karen

You can prep and have to from your current schema master.  Use adprep32 from the 2008 R2 media and you should be fine.

Thanks

Of course you can prep the forest and domain on a 32-bit DC. Using the 2008 R2 media, run adprep32.exe instead of adprep.exe. As the name implies, it is meant to run on 32-bit OSes and will do the schema changes just fine.
