I have 2 2016 domains. DomainA.local and domainB.corp. Separate forests. DoainA has our ERP software and related servers. Mainly an SQL server and an application which is accessed by a terminal server in that same domain. DomainB hosts all other servers and workstations. We don’t have Exchange. Using office 365 with our public domain name. I want to join the 2 domains into one domain name which is a sub of our public domain for example AD.public.ca
my goals are
-not to disrupt existing security settings for ERP and SQL in domainA
- to keep permissions on the file server folders in DomainB
- for users in DomainB to keep their local user profiles after joining the new domain.
what will be my best approach? Migrate using ADMT? Rename DomainA and merge DomainB with it? I don’t mind keeping the NetBIOS names as is. I just want the end result to be 1 domain which is a sub domain of our public domain AD.public.ca
