Is Exchange 2013 CU1 considered as a major release, which needs to be validate in Compatibility Chart?
I'm wondering if Exchange 2013 CU1 should be considered as a major release, which needs Symantec validation through Compatibility Chart document?
Because, until now, RU (Rollup Update) wasn't considered as a major release in opposite to Exchange SP (Service Pack). And Microsoft had annouce that starting Exchange 2013, the new servicing model will be CU instead of RU. There will still be some SP released.
I'm planning to migrate my Exchange 2010 SP3 to Exchange 2013 CU1 (which finally support coexistence) and my question was simple: is EV 10 SP3 supports Exchange 2013 CU1?
Thank you for help!
