Data Migration plugin makes it easy to migrate all or application specific data between two Countly servers. There are two migration modes;
In manual mode you simply choose an export folder in your source Countly server and data is exported into that folder as an archive and then you can import it into the destination Countly server via import from file process.
In automatic mode you create an import token in the destination Countly server and then use this token in the source Countly server to automatically transfer all the data. You can choose to redirect incoming data from the old server to the new one after the migration is complete.
