 -   You change the primary replica or the secondary replica to asynchronous-commit availability mode. After changing to asynchronous-commit mode, the secondary replica will remain in the HEALTHY synchronization-health state as long as data synchronization continues. However, if only the primary replica is changed to asynchronous-commit mode, the synchronous-commit secondary replica will enter the PARTIALLY_HEALTHY synchronization-health state. This state indicates that at least one database is in the SYNCHRONIZING synchronization state, but none of the databases are in the NOT SYNCHRONIZING state.
