Recently, I made the decision to migrate all of my servers over to the Interworx-CP system after previously having a single Interworx machine to work with over the course of the last four months. The migration of data and mysql was an extremely easy process, and I was overly impressed.
The only real issues come when migrating in “addon” domains from cPanel, in which I was forced to manually come up with a solution to take the place of this normal feature in the various other control panels in the industry. In order to do this, I created another httpd configuration in /etc/httpd/conf.d using the format accountdomain.com-addons.conf (accountdomain.com being the primary interworx domain for the account). When doing this process with over 200 domains, it got extremely annoying. :rolleyes:
The only other problem that I could come up with was not in the cPanel migration, but that of the Interworx --> Interworx migration. This process was simply to move accounts from one server to another, which worked flawlessly. On my previous Interworx server, however, I had quite a large amount of Bayes Spam Filtering data which I cannot find on the system to move over. What would the process be to go about this?
Anyway, thanks for the awesome transfer process - saved me a lot of time and effort and for that, it’s just another reason to use Interworx for absolutely everything. 
Any solutions to the Bayes database information transfer would be greatly appreciated so that I don’t have to start out from scratch again. But the major thing that I believe should be fixed is a way to transfer in addon domains and to create them from within a SiteWorx account would save me a lot of time as well
