Will be putting a new Windows 2008 R2 Server into a single domain network with two domain controllers, both running Windows 2000 Server. The functional level of the domain is mixed mode/2000.
Until a second 2008 DC can be purchased, I'd like to leave the current Win2k operational master DC as a backup DC as the other member servers running 2003 have either accounting/SQL or Exchange on them. Eventually all the w2k servers will be decommissioned, but until then, I need another DC for redundancy.
Following the standard process for adding a new DC, can I leave the old operational master DC (or the other backup DC) running after I transfer the FSMO roles to the new server? Will this cause any issues?
