We are looking at migrating from our current AD setup (parent + child domains) to a new forest utilizing a resource forest for Exchange. How feasible is this (based on info below) and how difficult? I’ve done forest to forest migrations before; but never from a forest/child domain to a new forest with Resource Forest.
Just wondering how painful it is to migrate from Parent holding Exchange, Child holding users to Resource Forest setup.
ParentDomain = holds Exchange server (and DAG) and a couple of DCs
ChildDomain1 = holds users, couple of DCs for ChildDomain1, and various resources for ChildDomain1
ChildDomain2 = holds users, couple of DCs for ChildDomain2, and various resources for ChildDomain2
Parent-Child trust between ParentDomain and each Child. Shortcut trust between ChildDomain1 and ChildDomain2
ResourceForest = will hold Exchange + DAG
Domain1Forest = will hold users and resources from ChildDomain1
Domain2Forest = will hold users and resources from ChildDomain2
Trusts built between ResourceForest and Domain1/Domain2. Trust built between Domain1 and Domain2.
