***UPDATE TO 0.974.3 BEFORE RUNNING THIS BUILD***  This build has a slight flaw in the upgrade code and it is recommended to use 0.974.55 instead.

This build is for 1.7.9.  If your server build doesn't support UUID's you will experience errors.  This is a very large and complex update.  Making a backup before upgrading would be a good idea.  If all goes well, almost all data should be migrated to the new format.  The only thing that will be lost by upgrading is the config file, which will be replaced with a new one.  (Your MySQL settings will be saved, however.)  You can make a backup of the old one so that it's easy to reconfigure the new one.  It also would be a good idea to run the command "/setlanguage english o", assuming you're using the default language and haven't made any modifications.  This will update all of the language file entries.
