I just noticed that one of my systems was still running 1.5.0 RC7: somehow when I upgraded to the 1.5.0 release, I missed this machine. Can I upgrade to 1.5.0 or 1.5.1 by simply installing the new version, or do I have to backup with 1.5.0 RC7 then restore with the new version? Normally I'd just do the backup and restore to be safe, but the database on this machine is 79 GB, and a backup/restore cycle will take a very long time!

Thanks for your help,

Dan.
