I have a running site (Site A).
I want to re-write the site fully to improve everything but, when I'm finished, I don't want to have to get everyone to sign up to the new site.
I wondered if I could create an entirely new site on a different domain (Site B) with a clean install of Wordpress - and then when I'm finished developing the site copy over the following tables from Site A to Site B: wp_options wp_users wp_usermeta
And would all my existing users then have full access to Site B (the new site) ?
Or is there more to it than this?
