Exchange multiple forest advice

Hello,

I am after some advice from fellow experts on how to tackle the below scenario with regards to Exchange migration and design

Current Configuration

Forest A - 1 AD Domain & 1 x Exchange 2010 server
Forest B - 1 AD Domain & 1 x Exchange 2010 server

Desired Configuration

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.

Questions

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

As you are already on Exchange 2010, it isn't going to make much difference, as cross forest is pretty easy on that version of Exchange. If it was an older version of Exchange I would have said upgrade first.

Therefore what I would do is build the new server for Exchange 2013, then cross forest migrate the users to that server, then migrate the Exchange 2010 users in the target forest to the new server. That will reduce the impact if something goes wrong. Don't try and do too much at once, cross forest is a huge impact as it is.

Simon.

Thanks for the prompt reply and sound advice Simon.
I agree a carefully thought out staged and managed migration is always the way forward :)
I've performed a few 2013 migrations but never had the need to do a cross forest move or configure a recourse/accounts forest model, so plenty of research and testing required I think.
