If the DB version is older than the BP version, then you have to upgrade it before you can log in. If however the DB version is newer than the BP version, then that BP version cannot use that DB, you can only use a compatible version of BP. Neither can you 'downgrade' the DB once it has been upgrade.

Please find below the error message   Connection failed - The chosen database has been upgraded by a version of Blue Prism which is newer than the current version. You may not use this version of Blue Prism in conjunction with the chosen database. Database version:233, Required version:217.   Can you please help.
