|PRE-UPGRADE CHECKLIST (upgrade)|
Take extreme care to back up any files from your current Geeklog installation that have any custom code in them, especially lib-custom.php (where all custom code should reside). Be sure to back up any modified themes, images, and static pages from your current installation.
Also, please be sure to back up your database. We can't stress the importance of backing up your files and database enough.
YOU HAVE BEEN WARNED.
