+Introduction
+ The purpose of this utility is to export data from Atlas to a ZIP file.
+
+What is Exported?
+ Metadata of all Hive databases and all entities connected to these databases (tables, columns, processes, paths) are
+ exported. To change the scope of export, modify the accompanying migration-export-request.json. More details of this
+ JSON file format can be found in http://atlas.apache.org/Export-API.html
+
+How Much Time Will this Take?
+ The duration of the export process depends on the number of entities present in your database. Approximately it takes
+ about 2.5ms for each entity in the database. For a database with 1 million entities, export will take about 40 minutes.
+
+Steps to Start Export step of Migration
+ - Shutdown Atlas. This is critical to ensure that no updates are being made to Atlas database while export is in progress.
+ - Execute the following commands in the host where Atlas server runs:
+ - unzip atlas-migration-kit.zip
+ - cd atlas-migration-kit
+ - python atlas_migration.py atlas-export.zip
+ if zip file path is no specified, exported data will be saved to a file named atlas-export-<timestamp>.zip
+ - To watch the progress: 'tail -f /var/log/atlas/application.log'.
+
+Next Steps
+ Once done, please use the Atlas Migration Guide for next steps.
