So I just completed my first ever upgrade of WordPress and I have to say that I’m very impressed with how easy it is. I just followed the directions of backup the MySQL database, backup the code files and copy over the new ones. My FTP program only overwrote the files that WordPress comes with and none – from what I can tell – of my customizations were changed. Of course, I didn’t hack anything core to the system, really, just installed some plugins and themes.
I haven’t fully tested all those plugins but some of the major ones seem to work. If anything seems broken, please use the contact form to let me know. And hopefully, that isn’t broken.
