 ## Migrate (Major version upgrade, for elasticsearch)
 
 This step is required when the user is upgrading Deepfence Management Console to a major release. It can be skipped in other cases.
 
+- Take a copy of backup files
+```shell
+cd ../
+cp -r deepfence_backup deepfence_backup_copy
+cd deepfence_backup
+```
+- Migrate elasticsearch data
+```shell
+docker run --net=host --rm=true --name=es-migrate \
+  -v ${PWD}:/data:rw \
+  --entrypoint=python3 \
+  deepfenceio/deepfence_backup:latest \
+  /usr/local/migrate_es.py
+```
+- `es_data.json.gz` is overwritten with new migrated data
+
 ## Import
+
+Connect to new management console / database, run following commands to import
+
+```shell
+docker run --net=host --rm=true --name=elasticsearch-restore \
+  -v "$(pwd)":/data:rw \
+  --entrypoint=/usr/local/bin/es-import.sh \
+  -e IMPORT_ELASTICSEARCH_MAPPING="false" \
+  -e ELASTICSEARCH_SCHEME="http" \
