5.2.3 vs 5.3.1 firmware for Lync deployments?


5.2.3 vs 5.3.1 firmware for Lync deployments?

We are on version 5.2.0 and looking to upgrade to the latest.  Is there an advantage in going to 5.2.3 versus 5.3.1?  I have been reviewing the release notes and I wanted to find out if the fixes contained in the 5.2.x train are included in 5.3.1.  Thanks!


5.2.0 released 09/2014

5.2.2 released 03/2015

5.2.3 released 05/2015


5.3.0 released 03/2015

5.3.1 released 07/2015

In our environment both 5.2.3 and 5.3.1 have been pretty stable.  UCS 5.3.1 has a pretty common issue where the welcome screen stays up after a reboot.  If you are using BToE and can work around the welcome screen issue I would recommend 5.3.1 as it will give you conferencing controls on the phone. 


If you are not using BToE or do not want/need on phone conferencing then 5.2.3 might be a better choice.


I believe 5.3.1 has all the fixes that are in 5.2.3 and most of the fixes that are in 5.4.0.

Wow that is grate news!  Will you be adding it to the community home page?  Right now it is pretty hard to find so you really would have to know it was there to go looking for it.
