224664 Transfer WP Blog to New Host

I have wordpress blog hosted on hostgator, and need it moved to another host. All settings, all themes, all posts, plugins, everything. I just need my blog moved. I have all accounts set up, all ftp info ready, all passwords and usernames ready. I just can't do it myself. I tried to do this myself and kept getting database errors. So I put the blog back to where it was and decided to post this project! So what I want is a bug-free transition of my wordpress blog from one hosting to another. As you will obviously know, it's not just a case of moving the files from one to the other. It will involve setting up a database or MySQL or something. I'm not sure, myself. So if you've done it before, please post :) Thanks! Lewis
