Does anyone know if EPO 5.3.1 is on schedule? I need something that supports SQL 2014 and 5.1.2 doesn't.
I don't think there is an upgrade path for 4.6.9 to anywhere currently. Yesterday I made the mistake of updating my 4.6.4 version to 4.6.9 because I assumed that the 4.6.8 listed as an acceptable upgrade patch to 5.3.0 meant 4.6.8 or higher. Fortunately I was working with a VM and had taken a snapshot before doing anything so was able to roll back easily, even after poking around the install guides for 5.0 and 5.1 I don't see 4.6.9 as an update path for anything.
4.6.9 can currently only upgrade to 5.1.2.
5.1.3 is still scheduled as follows which will most likely support SQL 2014. I don't have any timeline for 5.3.1.
RTS - week of 8/24/15
RTW - week of 9/21/15
