64Bit Domain Controller Into 32Bit Domain

[gearyw]

Hello All,

As part of our migration plan here, I'm in the process of building out new Domain Controllers to replace our aging Domain Controllers that are currently running. We currently are using Windows 2003 32bit as our domain controllers (we have 4 total) DC1,DC2, DC3 and chims01) and I would like to eventually upgrade to Windows 2008r2. I'm at the point where I'm about to run the Adprep commands on my primary DC (DC1 which holds all the fsmo roles), but will I run into any problems in this step? I know you can host a mixed DC environment with 32bit and 64bit but I wanted to get feedback from anyone who has done this migration before. I simply want to introduce this new DC into the domain for a few months until I am comfortable that it's ready to replace DC2.

Thanks all

Hi there,

You will not have any trouble running adprep, your domain level functionality must be 2k3 or greather.

If you plan to demote Win 2k3, you could check this topic:

You can find some interesting tips which can prevent mistakes.
