In the current state, the old HSQLDB data is also kept in the odb file
after migration. You can revert the migration by unzipping the odb
file and overwriting the URL in content.xml in tag
<db:connection-data>.

Besides that, the migration will be permanent only if you save the
document and a red circle on the save button indicates that something
has been changed.

Thanks,
