We have migrated everything so far successfully in our system.
We had a Lync 2010 Enterprise server in one site and pool and migrated to Lync 2013 Std by creating another site and pool. Same SIP domain, etc. Everything is working so far that we have tested.
My question is now is there a way to just move the PSTN gateway and trunk that shows in the shared components of the Lync 2010 site to the Lync 2013 site? The new mediation server has already been associated with the PSTN Gateway.
The same question applies for the Trusted Application Servers. This includes our Exchange 2010 UM.
