      • Add a TenantMigrationDonorHandler class that inherits from RecoveryUnit::Change (see example) in op_observer_impl.cpp with private members _databasePrefix and _state.
        • commit() can just be empty
        • rollback() should do the following (similar to SERVER-49179):
          • If _state is “abort” or “commit”, get TenantMigrationAccessBlocker for that “databasePrefix” from the TenantMigrationAccessBlockerByPrefix decoration, and and call rollBackCommitOrAbort on it.
      • Register TenantMigrationDonorHandler to the change to config.migrationDonors  onUpdate in op_observer_impl.cpp if the namespace matches  (see example).
