List of matrix flows - migration MAILBOX across two AD forests

Hi all,

Please find below some technical information about our Active Directory and Exchange infrastructure :

> 2 AD Forests 

> One Exchange Organization per-forest :

===> AD Forest A : Exch version > 2007

===> AD Forest B : Exch version > 2010

Note : there is no trusts between both AD forest currently.

We would migrate the mailbox from AD Forest A to AD Forest B and i need the complete list of flows and AD prerequisites for the MAILBOX cross-forest migration.

thanks a lot in advance.

Jiji.
