Hello Richard, You will have to upgrade the Exchange 2010 servers to Service Pack 3 prior to installing Exchange 2013 CU2 in the same domain. This includes extending the schema. When Exchange 2013 CU2 runs the pre-req checks, it will see Exchange 2010 SP2 and lower machines and then error / exit.
Thanks, Adam Farage, Principle Officer / UC Consultant Farage Consulting Solutions LLC ________________________________ From: [email protected] <[email protected]> on behalf of Sobey, Richard A <[email protected]> Sent: Friday, July 12, 2013 8:54 AM To: [email protected] Subject: [Exchange] Schema updates for Exchange 2010 SP2 and 2013 CU2 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
