Skype4B In-place Upgrade and LRS Admin Portal

While reading through the In-place Upgrade docs, I spied this little nugget:

Be sure to uninstall LRS Admin tool for Lync Server 2013 before running In-Place Upgrade. The LRS Admin Tool for Lync Server 2013 cannot coexist with Skype for Business Server 2015. After running In-Place Upgrade install the new LRS Admin tool, see Microsoft Lync Room System Administrative Web Portal for Skype for Business Server 2015

I haven’t tested this but the fact that they say to Uninstall the Lync Server 2013 LRS Admin Portal was the big catch. Make sure you read all of the docs a few times before you start the upgrade process.
