Microsoft released KB on Saturday 2nd May via its FAST PUBLISH process, so clearly there is some urgency behind this patch.
So what’s the issue?
As we know, when migrating from one pool to another, to maintain scheduled conference IDs we leverage the Conference Directory structure (in addition to SQL).
Prior to KB3062801, if administrators leverage the Lync Server 2013 Management Shell to complete the conference directory move to a Skype for Business pool, there is the potential for data to be lost, which will not provide a pleasant experience to your end users.
How can you fix it?
Apply May 2015 CU Update for UC Managed API to all servers within your estate, this will allow for management of the conference directories, using Lync Server 2013 Management Shell.
Are there any workarounds?
Yes – use the Skype for Business management shell to move your conference directory – not the Lync Server 2013 Management Shell! 🙂
