By backing up the database, QuickBuild actually saves contents of the database into a portable XML file, which can be restored to a different database. This way you can migrate data between different databases. For instance, if you want to migrate data from HSQLDB (the default database used by QuickBuild) to MySQL, the following steps should be performed:
Start QuickBuild and backup database to an XML file, say
data.xml.
Shutdown QuickBuild, and edit <QuickBuild
installation directory>/config.properties to connect
to MySQL.
Start QuickBuild again, and restore database from file
data.xml.
