I want to trial JBoss Nukes for a while with some friends, using the standalone version. If it's successful, I'll reconfigure and redeploy nukes on another JBoss server and use mysql.
How can I export the data that is built up within the CMS to another database?
you have to dump your base and redump it somewhere else. with mysql you use mysqldump tool and source command.
if you want to do cross database conversion it is more difficult because you have to convert scripts from one to other.
