Best way to migrate domain controller off of old server to new server
- Apr 17, 2020
Yes, it will work.
The prerequisite before introducing the first 2016 domain controller: domain functional level needs to be 2003 or higher.
I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then stand up the new 2016, 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.

It worked. SBS domain was 100% clean when I ran dcdiag and repadmin. Had a little fun when an error popped up saying it could not continue due to a compatibility issue with the SBS domain controller being a 2000 version. Had to do a one way update in two locations and then it worked. This SBS box has been running basically non stop since 2009. Time for it to rest. Thanks!!
