We added a 64 bit DC to our existing domain with no issues whatsoever early last year to add some horsepower to a site allegedly being hammered by Exchange and to test all our processes, documentation, 3rd party agents, services etc in preparation for the next HW refresh. We did it in the lab as well so we have had 2 forests running that way the better part of a year if you consider that "long term"
Test your 3rd party SW, AV, prepare your patching mechanism etc. By now it should be a non-issue but you never know. From: Webb, Brian (Corp) [mailto:[email protected]] Sent: Wednesday, January 07, 2009 7:37 AM To: NT System Admin Issues Subject: Upgrading DCs to 64 bit Has anyone upgraded their 2003 domain from 32 bit DCs to 64 bit DCs? 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.
