I'm going to build a new website for my brother's business. He currently is hosted at another provider. I need to build a new site at a temporary URL; when we're live, he'll forward his URL to the new one. Then we'll transfer his regular URL to DreamHost. Then, I need to move his new site (the one I build) from the temp. URL to his newly-transferred one here.
Am I looking at this correctly? His site needs to stay up during the re-build and transfer.
My question is this: HOW DO I transfer the site I build from one URL to another (Joomla, again, so it has MySQL and stuff... going to have a shopping cart too.)? I presume I'd need a new MySQL thing at the final URL, i.e., I couldn't simply FTP everything from the old to the new and expect it to work. Right?
I'm very familiar with the Joomla CMS; MySQL and stuff, not so much.
