Question
Is it possible to use a remote database server for Plesk and system databases?
Answer
Note: It is not possible to convert an existing Plesk installation to Plesk with a remote ‘psa’ database; it should be for new Plesk installations only.
Starting from Plesk 18.0.49 it is possible to use centralized DB (as Beta) and Network File System (NFS) for placing VHOSTs
