Migrate Domain Controller

Question

Hello,

If we only have one domain controller, can we migrate this dc to a new server? The existing dc have disk issue and should be migrate to a new one

Answer 1

Yes, absolutely no problem.

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new one, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.
