Common Area Phones have a contact object that is associated with the pool they were created for. In a migration scenario it is important to move all Common Area Phone contact objects to the Lync Server 2013 pool. Here is the process:
1. From the Lync Server 2013 Front End Server, open Lync Server Management Shell.
2. From the command line, type the following:
Get-CsCommonAreaPhone -Filter {RegistrarPool -eq "pool01.companyabc.com"} |
Move-CsCommonAreaPhone -Target pool02.companyabc.com
3. To verify that all contact objects have been moved to the Lync Server 2013 pool, from the Lync Server Management Shell type the following:
Get-CsCommonAreaPhone -Filter {RegistrarPool -eq "pool02.companyabc.com"}
