This thread seems to apply to my situation but I'm a bit confused in comparing the simple steps described here to the rather frightening and elaborate steps described in the WordPress Codex http://codex.wordpress.org/Changing_The_Site_URL
My situation is this:
1. I've built a WordPress site on a temporary URL issued by the hosting company (http://59.89.etc/etc/etc)
2. I am now ready to point the DNS for the actual domain (www.example.com) to the exact same directory and database etc. used by the temporary URL mentioned above. No files, folders or directories are being moved. Everything is staying exactly where it is.
3. Is it really just as simple as changing the WordPress address and Blog address in the General Settings? If so, why all the elaborate descriptions of changing names in database tables, editing config files etc. described in the wordPress Codex?
I really appreciate any response that helps me make sense of this.
