Some links broken after domain mapping

We recently setup domain mapping but now html links using the old address format, https://support.zoho.com/portal/<company>/helpcenter/articles/<article name>, now end up at a security error page. I've gone through and updated the obvious links to use the new mapped format, https://support.<company>.com/portal/helpcenter/articles/<article name>.

These links should either still work or be automatically updated when the domain maps.

If that isn't possible, a way to generate a list of all the links that use the old mapping so that they can all be updated manually would be a start.

Thanks,

Eric
