You must surely backup your database first!
After that, just be sure to install MediaWiki with the /config script,
and point it to your current database. 1.4.9 or 1.5rc4 installers
should upgrade you to the newest db schema (which is different for 1.4.x
and 1.5.x).
You'll probably want to merge your old LocalSettings.php customization
into the new one generated by the installer manually. I don't remember
any major differences from 1.3.x to 1.4.x for that.
Good luck. :)
