The Master Vault (also-known-as-knowledge-vault-master) can be deleted by accessing the Delete Master Vault command from the Tools menu in the Autodesk Data Management Server Console.
The Delete Master Vault operation permanently removes the database files that are related to the Knowledge Vault Master.
No Vault operations can be performed after deleting the Master Vault. You will have to create a new Master Vault in order to perform Vault operations again.
When working in a Connected Workgroups (also-known-as-full/database-replication) environment, the Delete Master Vault operation is limited to the Publisher workgroup.
Delete the Master Vault
Launch the Autodesk Data Management Server console.
