You need to change the url from vcenter, the request is if you are able to change from GUI (Graphical User Interface)
There's no option to do this from the interface, and the only way would be to delete and recreate the connection. However, since you have many objects imported from vCenter, you are concerned that they might be lost, along with the associated policies.
Open a Support case, Support team can help to modify mysql directly to make this change.
