Exchange 2010 and 2016 Coexistence With DPM Questions

Hello

Trying to get my environment ready for 2010 /2016 coexistence.  I will need to backup both for a period of time and want to make sure I get the process right.  My understanding is Eseutil is backwards compatible so the newest version. Is that correct? However What do I do about the path for ESEUTIL?  The current fsutil hardlink points to "c:\program files\microsoft\Exchange Server\V14\bin\eseutil.exe"

My 2016 server has installed with the followign Exchange path:

C:\Program Files\Microsoft\Exchange Server\V15\Bin

2010 has the following ESE Path: 

C:\Program Files\Microsoft\Exchange Server\V14\Bin

How should I update the fsutil hardlink so that both the 2016 and 2016 will be able to backup?

Anything else to be aware of for the co-existence with DPM?

Thanks

Phil
