Single Forest rename
Posted on 2011-02-15
We would like to rename our Forest due to conflicting issues in our network... current Forest FQN is ad.company.local we would like to rename this to ad.company.corp. currently we are migrating from 2003 DCs to 2008 DCs, once finished we'll be renaming the Forest before we migrate from Notes to Exchange 2010. Is there any best practices for this or any recommended way? i can find a lot of material on domain rename but not forest....
Can we create a new AD Forest create a 2 way trust and migrate objects with ADMT to the new Forest?
Or do we rename the forest root once we have upgraded all the servers to 2008? (is the rename even possible?) then join the machines using a netdom batch file or is there any more advanced tools?
There's about 400 machines to migrate and i'm cautious about users not being able to access resources with the sIDHistory attribute, once users have been migrated and the down time of machines.
Any advice is appreciated
