Thread:Project:Support desk/Backing up a personal (offline) wiki

Hello, I have an offline personal wiki that I use to manage information relating to my writing. I would like to upgrade my computer to a SSD HD and a 64bit version of windows. I have read a few of the mediawiki backup guides but I am wondering if anything is different for backing up an offline wiki and/or changing from a 32bit to 64bit OS?
