I have been running a mix of 32 and 64-bit DCs for over a year with no ill effects at all. I prefer the performance gains I receive from running 64-bit, but not all MS management tools (GPMC in particular) would run on 64-bit prior to Server 2008's release, so I had to keep at least 1 32-bit server around for that purpose.

Our security team wants to move to 64 bit to take advantage of the larger event logs - anyone done it? Were there any issues running some DCs 32 bit and some 64 bit? Anyone run a mixed environment long term? I'm planning on doing some testing, but wanted some advance scouting if available.
