Wordpress: moving from subdomain -> root strategies
This is sort of a "best practices" question; my situation's got to be fairly common (maybe just too simple!) but I'm not seeing anything really similar, so:

I'm updating an old Mambo site hosted on 1and1. I've been developing the new Wordpress version locally using MAMP, but client wants to finish it somewhere on the live domain (they have a lot of content to input), then move to the main domain.

1and1 tech help said to proceed this way: install WP at mysite.com/wordpress, add the subdomain dev.mysite.com, and map it to the subdirectory install. Then for wp-config, Site URL and Blog URL both would be dev.mysite.com. When the time comes to move to mysite.com, use Wordpress' [pre-existing subdirectory install][1] method to move to the main domain.

Is this the "best" (read: least painful) method to do this? 1and1's scripted WP install isn't a complete version, so I have to do a manual install in any event. Any advice welcome.
