Symptoms
Assume that you create Response Group workflows that contain the same holiday set names in a co-existence environment that has Microsoft Lync Server 2010 and Microsoft Skype for Business Server 2015. When you run the Move-CsRgsConfiguration cmdlet to migrate Response Group configuration settings from Lync Server 2010 to Skype for Business Server 2015, the result says that the holiday set names are conflicted, and recommends adding a non-existing ResolveNameConflicts parameter in the cmdlet.
Cause
This issue occurs because the Move-CsRgsConfiguration cmdlet isn't designed with the ResolveNameConflicts parameter.
Resolution
To fix this issue, install the November 2015 cumulative update 6.0.9319.102 for the Skype for Business Server 2015 Response Group Service.
