I was looking for information on how to migrate domain info from a Windows 2008 R2 server VM to a new 2019 server VM. I found info that essentially says to install a new 2019 server on the domain, promote it to domain controller, transfer all AD roles, then un-promote and decommission the old server (nothing specifically about VMs). This may be a dumb question but I'm learning - is there any way this process would be different on a VM? I believe it is hyper v. Or does the same thing apply? My assumption is it works the same way but in case I'm missing something I appreciate if anyone can shed some light on that.

Thank you,

    You must migrate from FRS to DFSR prior to promoting a Windows Server 2019 Domain Controller, so make sure you've done that before attempting to promote the new DC. – joeqwerty Oct 22 '20 at 13:43
  • Mentioning that just in case: Reverting to an earlier snapshots as a fail sage mechanism for borked migrations is most likely going to make it worse. – Daniel Oct 22 '20 at 15:25
  • @joeqwerty yes that I've also seen but thanks for the reminder! – mwirk Oct 23 '20 at 19:12
  • @Daniel could you elaborate on that - why would it make it worse? – mwirk Oct 23 '20 at 19:13

Your assumption is correct, there is no difference at all in the process if the involved server are physical or virtual.
