An update for Lync Server 2013 has been released just one month after the previous drop but with some important bug fixes. One of the large annoyances fixed is the Dial-in conference rejecting the PSTN caller with a message about the meeting not found (2995830). There have also been some recent reports about maximum followers reached when that is not the case as well as high IIS CPU utilization – all addressed (well high IIS when publishing the topology has not been but I personally have never seen that issue).
There are is a database upgrade required for the backend databases, none for the CMS (assuming you are up-to-date). 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.
