Hi,
the features inside of Exchange will not have a effect on the support statement and the related matrix. As the backup in the back is done using VSS provider, from backup point of view there is no change how the backup is done.
So, suppose, it will work as it should work. Please keep in mind too, that in case you want to migrate to Windows 2012 R2 and Exchange 2013 SP1, you need to wait for DP 9. With this version the special combination becomes supported.
Best regards
Daniel
