Known limitation:

  • “MySQL Router” VM is pending migration to track 8.0 (currently used by legacy charm).
  • PgBouncer VM provides legacy charm through latest/stable.
  • PostgreSQL VM+K8s provides legacy charm through latest/stable.

Feel free to contact us, see details below, if you are considering migrating from other “legacy” charms.
