Current environment is Exchange 2010 SP3 RU5 supporting 4,000 Users. Client estate is Outlook 2010 SP1 going on SP2.
We're pulling our Archiving solution away from 3rd party and back into Exchange. Implementing a new set of Exchange 2010 Servers (old DAG or in a new Archive DAG) would be easy. But is there Exchange 2013 stepping stone potential?
Can the Archive DAG / Archive mailboxes be on 2013? i.e. for any given User, leave their primary mailbox on Exchange 2010 and create new Archive mailbox on 2013.
I want to avoid implementing 2010 Archive Servers and then go 2013 Archive 6 months or a year later.
This article suggests 'no':

"Locating a user’s mailbox and archive on different versions of Exchange Server is not supported."
I've found little info but the odd statement here / there.
Is this the latest position? Is it that cut & dry? Anyone tried it? Why won't it work (or will it but it's not supported)?
Thanks!
