Our office is getting ready to move to a new building. We have a single Windows domain. We have two W2K DC's, both GC's. We're also running Exchange 2K3. Lets call our DC's A and B. Right now, B has all of the FSMO roles. B is also listed in Exchange System Manager as the primary DC for RUS and listed as the first entry under the Exchange Server properties, Directory Services tab (domain controller A is also listed)
Our current plan is to move DC B over to the new building this weekend. However we want to take DC B down at some point this afternoon and then move it over the next two days. Obviously, we won't have it's services for up to 48 hours. We have two other sites although they each have only one DC. My question is this, should we transfer any of the roles over to DC A while DC B is down? We'll be setting up a new site in AD for the new building until we have everything moved over. My understanding on Exchange is as long as it can talk to a Global Catalog server, it will continue to run properly. Any advice? I'm inclined to transfer roles over since DC B will be down for 48 hours (hopefully no longer). We're in a time crunch so any input is appreciated! Thanks.
