Hi team,
There is a client with Domain Controller (2008 R2) running together with Exchange Server 2010 SP3. However there were some huge problems with Exchange and DC therefore since the best practice is to keep those roles seperately, they are in need of doing so.
Can someone please suggest me the best approach? The server they use right now is with 16GB therefore whatever done, Exchange should be on that machine and DC on the other 6GB.
Option 01.
- Both Exchange and DC are together
- Install new Exchange on a temporary Server and move everything make that Exchange server the only working primary
- Remove exchange from the DC server
- Promote new Additional DC and promote it with FSMO and make primary
- Demote the old DC from the 16GB server
- Install Exchange again on the 16GB server and move everything from the temporary server
Or Option 02
- Add new additionall Domain Controller server and make it primary with GC and FSMO
- Run dcpromo to demote the old Domain controller role from where the Exchange Server too is installed
- Once DC role is removed from the exchange server, set up DNS and perform a restart, so Exchange will identify the new GC and domain controller
- Live happily ever after
Thank You,
Cheers!!
