Searching for Orphaned Objects

Recently when decommissioning a Lync 2013 pool, I ran into an issue where it said that by publishing the topology and removing the pool I would orphan existing users, endpoints, or devices:

Consult your Skype for Business Server documentation to learn how to move or disable objects still homed on the pool. To find those objects, execute the following cmdLets: Get-CsUser, Get-CsExUmContact, Get-CsCommonAreaPhone, Get-CsAnalogDevice, Get-CsRgsWorkflow, Get-CsDialInConferencingAccessNumber, Get-CsAudioTestServiceApplication, Get-CsTrustedApplicationEndpoint, Get-CsPersistentChatEndpoint.

Now I knew there were more objects that could trigger the orphaned objects failure, so I also ran Get-CsConferenceDirectory, Get-CsTrustedApplication, Get-CsTrustedApplicationComputer, Get-CsTrustedApplicationEndpoint, Get-CsTrustedApplicationPool. The only result I got was aCsAudioTestServiceApplication: 

I attempted to remove this however there is no remove cmdlet, and there is no option to set it's registrar pool with Set-CsAudioTestServiceApplication. 

I confirmed with one of my co-workers that it was not possible to remove this, however it should not be an object that prevents the removal of a pool. So what was causing the hold? 

I decided to go into the weeds and dumped all user objects from AD to a CSV via CDSVE ( csvde -f test.csv -r objectClass=user ), and then searched for all users who had the msRTCSIP-PrimaryHomeServer value that matched the Lync 2013 server. Low and behold there was a Lync Room System object that was still homed to the Lync 2013 pool. After moving this object to the new S4B pool, I was then able to publish the topology.
