Any errors during the import ?

This sounds very similar to a problem i had.
I solved it by changing the chmodes:
directory chmode 777
files chmode 666
(in the old board)

Still dont understand why it does not recognize the members and cgi-bin behind the web root either.

I had the same problem.
But it worked for me moving the complete /cgi-bin directory into web root (before: /var/www/vhosts/url.com/cgi-bin after moving: /var/www/vhosts/url.com/httpdocs/cgi-bin)
