Apps from non-existent server

Dear all,
some time ago we turned off our Kopano Server (ucs member, VM) and later deleted it. The DC still shows Kopano Core,Webapp and Z-Push as installed. How can I make the DC forget about these Apps? The old server is gone for good, so I cannot uninstall them the regular way.
Thanks for your help!
Best regards
KaBi

The solution was easier than expected. By removing the server from devices, the primary dc “forgot” about the orphaned apps.
