<!-- ## Project Metadata

The metadata is stored in meta directory in project level, database level, and API level.

Under ``Project Metadata``, you can perform the following operations.

- Export all metadata from the meta tables to meta directory
 
- Import all metadata from the meta directory to meta tables
 
- Export project meta to zip file and download
 
- Import project meta zip file and restart

- Clear all metadata from meta tables

<alert>
  Import won't work with zip files exported from the older version of apps (< 0.11.6). <br> 
  Import / Export will only transfer metadata and files related to the project and not any table data in the project.
</alert>

## Migration Example

### Export Metadata

From the source project, go to `Project Metadata`. Under ``Export / Import Metadata`` tab, select ``Export zip``, click ``Submit``. This step extracts project metadata and stores it in compressed (zip) format.

### Import Metadata

From the destination project, go to `Project Metadata`. Under ``Export / Import Metadata`` tab, select ``Import zip``, select ``meta.zip`` file stored in previous step. This step imports project metadata from compressed file (zip) selected and restarts the project.
