[Exchange] Schema updates for Exchange 2010 SP2 and 2013 CU2

[Sobey, Richard A]

Hi all,

We're looking at deploying Exchange 2013 CU2. First we need to go to 2010 SP3. 
Can we avoid doing two schema updates by applying ONLY the 2013 CU2 changes, or 
MUST we use 2010 SP3 first, and then 2013 CU2?

Disclaimer: I haven't Googled for this information at all. Lazy.

Thanks

Richard
