hi, I recently changed web hosts, and I'm reinstalling all my files. previously with my old host I had wordpress running from a subdomain, however this time I registered a domain name and I'll set that up as an addon domain in which to run wordpress from. now, my question is, how much from this guide (http://codex.wordpress.org/Changing_The_Site_URL) do I need to do? I don't understand in which situations I would need to do everything on that page, or just one thing. like, the first part, "changing the url" sounds like maybe that is all I need to do.
also, my addon domain points to a sub folder such as subfolder.com, so if I do need to change the url in my DB, do I change it to my new domain since it will be and addon, or do I change it to the url that points to the subfolder, like: domain.com/subfolder.com? thanks, and hopefully this isn't too complicated for me, lol.
