Merging two domains

[Guest]

We have two different domains in two different forests (and different subnets, of course) and we would like the second domain to merge into the first one (that is, the same namespace and common users). Is ADMT version 2 the only way to go

Thanks in advance
Marcus

Marcus,

ADMT2 is the way to do this, unless you want to buy third party tools (which
are available).

thanks for your prompt reply. I thought of ADMT as the only way in order to move users and SIDs but I have a few doubts about domain controllers afterwards. I mean, there are two domains (ABC.com and XYZ.com, 3 domain controllers and roughly 70 clients in each) and we need to get rid of XYZ.com and XYZ.com's Domain controllers have to join ABC.com's structure (that is, a single domain with 6 domain controllers and 140 clients). Clients need to be configured to join ABC.com and existing DC in XYZ.com need to be configured to join ABC.com (removing AD and destroying XYZ.com domain). Is that correct

Yeah - you got it. ADMT will migrate the machines to the new domain. Once
you've got everything migrated, you can demote the XYZ DCs, and promote them
into ABC.com. Use dcpromo to remove them from XYZ, and then use dcpromo
again to add them to ABC.

Thank you Brian
Yeah, I got it right but I admit it's gonna be a hard work with those domains ;-

Happy new Year
