Restore Exchange DB from one forest to another and use ADModify to fix attributes?

Nov 13, 2007 at 6:42 PM
Is it possible to restore an exchnage 2003 database to a different exchange 2003 server in a different forest and use the ADModify on imported users to make email work? Big task i agree but we are running out of time getting normal migration methods to work due to a really poorly designed and maintained forest. I saw the articles below that made me think this might be possible.

Appreciate ANY help!

It's possible but in that scenario you're probably better off doing something like:

- Get DB mounted in the new forest
- Clear Exchange Attributes on the imported users
- Use mailbox recovery center to reconnect the mailboxes to the imported users

Of course this is a simpflication and scenarios can vary widely, but this is one method you may consider that doesn't require admodify.
