While "safe computing" says to split off your schema master while doing the upgrade, I've not seen it be an issue anywhere, except folks that had the old SFU schema changes and hadn't already applied the R2 schema fixes. Truly a non-issue.
You can run a domain with 2000, 2003, and 2008 DCs and GCs; although you gain a lot of functionality by being at least at 2003 native for both DFL and FFL. Regards, Michael B.

Currently I have three domain controllers. I'm planning on demoting a DC, removing it from the domain, wiping the box, installing 2008, then run the necessary adpreps... anything else to take into consideration? I can keep the other two domain controllers running 2003 and leave the domain in mixed mode can I not? I also have a 03 member server running 03 exchange if that makes a difference. Any ssuggestions or caveats appreciated. Steve ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
