Hi Team,

I have question, I want to migrate my exchange 2007 to 2013.

right now exchange 2013 already provide CU7. 

My question is, is exchange 2013 CU7 compatible with Exchange 2007 SP3 lattest RU (SP3 RU15) ?

is there any limitation of version if i want to upgrade Exchange 2007 to 2013

Thanks Before

Hello,

The first thing I would say, is that the MINIMUM supported update for Exchange 2007 is SP3 RU 10, so you should be ok with RU15 installed with Exchange 2013 Cu7.

The second thing I would say, and I am not sure how you're current environment is configured and how you plan on configuring your future environment, but if you are using Public Folders, Exchange 2013 CU7 changes the way public folders are handled during coexistence.  I would recommend taking a look at this blog post from The Exchange Team
