Backup Exec 2014 / GRT of Exchange 2010 and Exchange 2013

Group,

I am trying to determine if BE 2014 will do GRT backups of Exchange 2010 and also Exchange 2013. 

Current environment:

• Older server hardware to be retired later in the year.

• Backup Exec 2012 v-ray edition / deduplication folder.

• Exchange 2010 with GRT backups.

• We have a current Sym support contract and I have the codes to install BE 2014.

Future environment:

• New server, yet to be purchased.

• Backup Exec 2014 v-ray edition / deduplication folder.

• Exchange 2010 with GRT backups.

• Exchange 2013 with GRT backups (after we build a new server and migrate to Exchange 2013).

http://www.symantec.com/business/support/library/BUSINESS/xCL/TECH217478/be_2014_scl.html#agent_for_applications_and_databases_compatibility-microsoft

The above SCL says this:

“To run Exchange 2010, the Backup Exec server must run on Windows 2008 SP2 or on a 64-bit Windows 2008 R2 computer on which the Exchange 2010 Management tools are installed.”

That means (to me) that I need 2008 on the new Backup Exec media server, not 2012.  But elsewhere in the above SCL I will need 2012 on the media server and a domain controller to do GRT of Active Directory. 

So should I put 2008R2 or 2012R12 on the new server, yet to be purchased?

Thanks all!
