 - `--service-filter` or `-s`: you can filter on services for migration commands (like run against only ATLAS or RANGER), possible values: ATLAS,RANGER,LOGSEARCH
 - `--skip-cores`: skip specific cores from migration (can be useful if just one of it failed during restore etc.)
 - `--collection` or `-c`: run migration commands on just a specific collection (like: `ranger_adits`, or `old_ranger_audits` for restore)
+- `--core-filter`: can be used only for index migration, that will work as a regex filter on the snapshot core folder e.g.: "mycore" means it will be applied only on "/index/location/mycore_folder" but not on "/index/location/myother_folder"
