You can unregister but not delete the EUQ
database from the system through the web management console. Unregistering
a database means that the database will still exist, but it will
not be used by IMSS.
Procedure
Go to Administration → IMSS Configuration → Connections from the menu.
The Components tab appears by default.
Click the Database tab.
Select the check box next to the unwanted EUQ database
server.
