First of all, tell to all users to keep out of PDMS while you make this maintenance, after you confirm all users are out, then you Lock the project, don´t forget to savework after locking.
Then, use the expunge all command just to make sure there are no users stuck in the project, after that Expunge the Claimlist, select all db´s of your project and Expunge it all.
Hope it helps...
