I am trying to remove my single server Lync standard install via the Topology Builder.

By going in to my site -> Standard Edition Front End Servers -> Delete, i get the error A published pool hosting Central Management Service can not be removed

I cant remove the server from the topology so cant run the deployment wizard which will remove the role from the server.

As an edit from a post, I have now done the following:

  1. Lync Control Panel -> Deleted all the Lync users from Lync -> commit all
  2. Get-CsConferenceDirectory | Remove-CsConferenceDirectory
  3. Get-CsExUmContact -Filter {RegistrarPool -eq "hqslc1.domain.local"} | Remove-CsExUmContact
  4. Get-CsRgsWorkflow -Identity:Service:ApplicationServer:hqslc1.domain.local | Remove-CsRgsWorkflow
  5. Get-CsDialInConferencingAccessNumber | where {$_.Pool -eq "hqslc1.domain.local"} | Remove-CsDialInConferencingAccessNumber
  6. Get-CsCommonAreaPhone -Filter {RegistrarPool -eq "hqslc1.domain.local"} | Remove-CsCommonAreaPhone
  7. Get-CsCallParkOrbit followed by Remove-CsCallParkOrbit -Identity "Home Park Orbit"
  8. Lync Control panel -> Voice Features -> Unassigned Number, delete, commit all
  9. Lync Control Panel -> Voice Routing > Route -> Edit -> Select all -> Delete -> Commit all

Despite the above, I still cannot remove the server or when running the Remove Deployment wizard no changes are made.

You need to delete the pool created before you can run the Topology Builder.

Which is Phase 3 & 4 of the Decommissioning a Deployment guide for Lync:
