TypeDB Upgrades

There are two mechanisms in which data can be preserved during a server version upgrade:

  • If the new version has the same data format as the old one, it should be done by reusing or copying the data directory.

  • Otherwise, it should be done by using the Database Export & Import tool, which would take care of migrating the data into the new format.

Preserve data by copying the directory

To do this, simply shut down the servers of the old version, and copy the database to migrate from the data directory (set with the --storage.data command line argument) into the data directory of the new TypeDB server installation.

Alternatively, just start the new server making sure it uses the same data directory path as the old one.

Preserve data using the export/import tool
