To clarify, the transfer toold does transfer public_html data from cpanel. Its just that the host DocumentRoot changes for the primary domain.
/home/user/public_html/ - cpanels primary domain.
/home/user/domain.com/html/ - destination when transferred to interworx.
/home/user/domain2.com/html/ - destination if secondary domain.
Subdomains differ a lot on interworx. I think we changed the import to force these to be treated as secondary domains. But just in case we didn’t on interworx subdomains are handled via a rewrite and go to paths like:
/home/user/domain.com/html/sub.domain.com/ - or
I’d recommend using the secondary domain system for subdomains rather than subdomains if your coming from cpanel, it will work more in the way you expect.
We do have a symlink going from:
/home/user/public_html/ to /home/user/domain.com/html/ - but only for te primary domain.
