Exchange 2010 migration to Exchange 2013

Hello all,


I have reviewed. 






What I gathered from the articles I have read are that I will have to install another BES server, connect it to Exchange 2013 with the changes to connect to Exchange 2010 as well until the migration is complete.  Is this correct, or can I simply make changes to the current BES server to connect then proxy back to 2010 mailboxes?


What is the best solution?

We have a setup for migration from Exchange 2007 to 2013 where we only have one BES Server. BESAdmin mailbox must be on 2013 and users still on 2007 automatically proxy through 2013.

This scenario is commonly referred to as "Exchange mixed mode". It is supported by Blackberry.
