Updating
From Sfiabwiki
Updating from a previous older version
Updating SFIAB to the newest version is very straightforward, assuming you havent made any crazy custom changes to the source code. Head on over to the Download Page to get the latest version, either as a .ZIP or a .TAR.BZ2
If you have a 'stock' installation without any changes, simply download the new source code file, and uncompress it over top the old files. If you are updating a remote server, you can uncompress the file locally and FTP each file up overwriting the ones already on the server.
If you have made custom changes, you'll need to go through and re-merge your custom changes into the new codebase... if you've made custom changes we'll assume you know what those changes are and how to re-incorporate them :)
Once you have uploaded, uncompressed and/or merged every file (and I do mean every!), you'll need to run the db_update script to update the database tables and layout to the required version. To do this, simply point your web browser at:
(your sfiab website)/db/db_update.php
You should see it run through a bunch of different versions and let you know that its installing them. Once its done, head back to your main SFIAB page and everything should be ready to go!
