Thread:Project:Support desk/Upgrading MediaWiki in MoWeS Portable?/reply (2)

Attempting to follow these instructions DELETED my entire database.

I've been able to partially restore it (drag & drop, overwriting the files), by using a zipped file that contained the entire contents of my Mowes directory... but it wasn't current, and I lost several weeks worth of very hard work.

Needless to say, I am PISSED at the above person.
