Currently windows 2k3 SBS is acting as dc, dhcp, dns, exchange, sql.
Now we are about to replace it with sbs2011, we have decided to go for fresh installation and transfer data, export emails. Due to SQL requirements by web apps we can't remove current sbs server so there will be 2 DC with same domain name. Planning to disable dns, dhcp etc after connecting sbs2011 then disjoin all the computers and join to new domain. My only concern is - do i need to disable AD? or what's the best solution to get going with new server and old server together so that SQL can be still used from old server SBS and all other services of SBS can be used from SBS 2011. Or once I disjoin and join all the computers to new SBS 2011 domain i don't need to worry about old SBS server AD/domain. Thanks
