Thanks for the reply. All the members files are under /cgi-bin/ubb/Members/, and all I have under /httpdocs is /ubb, which holds the Forum1..Forum_n folders.

I had to change the vars_config.cgi when the new site was under a new URL (www2), but with the URL registration change, the new server will have exactly the same URL as the old site, and the old site will not be accessible via the Internet. So with the copy, I am actually wiping out the vars_config.cgi in cgi-bin/ubb and replacing it with the old one containing the correct URL
