Running 7.1.1 and having issues upgrading to 7.3.x. I tried following this process (link below), but I could never figure out how to connect to mysql. I made sure the mysql jar file was still there. It sounds like there is supposed to be a wizard that appears? But I could never find it. I searched all over and it sounds like I need this "wizard" to appear. What's the secret? Thanks.
