Something I just thought of, not sure if there would be a demand for such a feature, but I guess it can’t hurt to post.
I was thinking of having a way to export all the settings to a file. If you move to a new server you can just run that one config file you created on the pervious server and it will setup all the siteworx accounts, DNS, etc. for you. You could then use the website backups to restore the websites or just zip the entire /home directory and copy it over the new server (excluding the iworx folder) or include the zip file information in the main backup config file.
