Migrating windows 2008 domain controller to 2016 Domain Controller
HiVishwa10
Please advise if you would like to do a clean-install on a different server or migrate on the same server (In-place Upgrade)?
Firstly, when replacing / Migrating a DC, I would always like to make the new DC have the same IP as the old DC. It simplifies many things, like DHCP scopes, DHCP relays, and devices with static IP. You can give the old DC a new IP and then give the new DC the original IP address.
Thank you,
Dav,
Should not be a problem but do not do an in-place upgrade. In-place are risky and possibilities of corruption carry-forward. Server 2016 still works with older FRS technology.
I'd check that domain functional level is at least 2003, then 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, transfer pdc emulator role, use dcdiag / repadmin tools to verify health, when all is good you can decommission / demote old one and move on to next one. Also at some point either before or after I'd recommend migrating sysvol replication from older FRS technology to DFSR.
