Hi Team

I've run in to a scenario where a company ABC acquired another company XYZ.

What the company would like to have is run both of these domain separately however the communication should be present between these two domains for all resources

A single forest with multiple domain

How do we achieve this?

I know there is ADMT tool for migration one domain to another. But in this scenario, we are not migrating just adding it under a single forest. ABC is being the Forest then ABC domain, XYZ domain under it,

Thanks in advance
