Notes 

Note

The input parameters consistency_group_id and enable_quick_mode were removed in version 3.4.0. These were deprecated due to internal API simplification and are no longer supported.
Connection type gateway was removed starting from version 3.4.0. Please use an earlier version if you require this connection type.
