I am after some advice from fellow experts on how to tackle the below scenario with regards to Exchange migration and design
Forest A - 1 AD Domain & 1 x Exchange 2010 server
Forest B - 1 AD Domain & 1 x Exchange 2010 server
Forest A - Upgrade/Migrate to Exchange 2013
Forest B - Migrate mailboxes from forest B to forest A but leave AD accounts in forest B so the mailboxes become linked mailboxes in forest A for forest B users
I was planning to migrate forest A to 2013 first and then migrate cross forest from forest B to forest A.
I'm not looking for a step by step, just some input from other experts.
- Anyone have any issues or concerns on what I am proposing?
- Would I be better off performing the cross forest moves before attempting to migrate forest A to 2013?
Any help or ideas greatly appreciated
