So, two sites with DNS and AD servers going away.
Main site remaining with own DNS and AD.
WAN communication is over s2s hw BOVPN firewall/routers.
Single forest, email server at main site.
The two sites going away, sold off, what would be the best way to remit control to new owners?
I say, copy emails to separate db and hand it over to new owners when ready.
Demote (dcpromo) servers ; ensuring AD health first.
no reason they should want to create a trust relationship between domains(forest).
Two separate companies not related.
Anyone have other ideas/bullet points?
