ISE 3.4 Patch 3

Hi everyone! 

Good day and greetings!

Does anyone here upgraded your ISE devices to 3.4 Patch 3? Did you guys encountered any issues and bugs?

Got our 3815 appliance in almost 2 weeks ago. Came with 3.3 installed, so went ahead and set an IP address and got it online. Installed 3.3 Patch 8 and then upgraded to 3.4 Patch 3.

Could not perform a config backup after the upgrade. Apparently there is no info for the 3815 appliance in the platform properties and so it isn't being properly profiled as a 3815 appliance. So memory allocations are lower than they should be.  However it does report back as a 3815 appliance.

Have a TAC case open and they are looking into it.....
