February 2015 Lync Client/Server Update

Microsoft quietly released the Lync Client and Server CU for February 2015 and perhaps with good reason; little to nothing appears to have been added to Lync other than a not quite functioning correctly  CsClientPolicy setting EnableSkypeUI. The policy is designed to allow a Lync 2013 server admin to preserve the look and feel of the Lync client after the 'Skype' CU has been delivered either automatically via O365, via Windows Update, or via the system administrator. By default this value is $NULL which SHOULD equate to ‘Use the Lync UI’ but instead it defaults to ‘Use the Skype UI’. Setting the value to $FALSE will force the Lync UI and in future client releases (read that as RTM) the feature will work as expected.

Missing/odd features is definitely not a reason to apply a patch and since it has been 30 days since the release with no known/major issues I would say all is good. The patch does update Core, Server, RGS, Management, and Web Components as well as databases.

There are a few database upgrades required for the backend databases (QoE), and for the CMS (assuming you are up-to-date (i.e. since December 2014)). It is interesting that Microsoft is calling out the sequence with more vigor and I cannot stress enough how important it is to make sure your databases match your CU level or ‘bad things happen.’  We discuss over and over how to check upgrade readiness as well the database upgrade methods so if you are unclear, review previous posts here.
