Switching Back from Manual DNS to Pointer Domains

For a long time now I’ve had one site with multiple alias domains configured manually via NodeWorx and some hacks in config files. This solution was given to me by someone here and InterWorx via a trouble ticket (I think).

Since pointer domains are now available I’d like to not use the manual method and use pointer domains. Herein lies the problem; I have no idea what the hacks were. I deleted the DNS records out of SiteWorx but adding pointer domains can’t happen yet because of those hacks. Any input would be GREATLY appreciated.
