The database transfer tool in Moodle 2.3.2 onwards enables an administrator to migrate their Moodle site from one database to another, for example from MySQL to Postgres.
The tool is currently classed as an experimental feature and may be found in Settings > Site administration > Development > Experimental > Database migration. There is also a command line script in 'admin/tool/dbtransfer/cli/migrate.php'.
The dbtransfer tool uses the XMLDB schema definitions from Moodle and installed plugins to retrieve the data from one database and transfer it another.
