    ======= INCOMPATIBLE DATABASE DETECTED =======
    Your database is set up for use with a MySQL or MySQL-compatible variant.
    This installation of OpenProject no longer supports these variants.

    The following guides provide extensive documentation for migrating
    your installation to a PostgreSQL database:

    This process is mostly automated so you can continue using your
    OpenProject installation within a few minutes!
