Is anyone aware of either known issues or supported configurations between the binaries of AX 2012 R2 and R2 with CU6 installed. For example, is it safe for a CU6 client to connect to an R2 AOS, or even an R2 client to connect to a CU6 AOS.
I had read somewhere in the past that as part of hotfixes and cumulative updates (a collection of many hotfixes) that Microsoft would not create binary and AOT dependencies, but I can no longer locate this blog article, and additionally I have seen such dependencies in recent years.
