I have 2 domains, domainA is a hosted domain and domainB is a domain alias of domainA. Both domain names are hosted externally with the name servers set as ihost. I'm running DNN with a potal for each of the domains. Everything is working except I want separate email for both domains. I realise now that they should have both been separate hosted domains but both sites are now built and running on the same DNN database.

 What is the best way to separate these so I can have separate email for each domain.

 I thought that on the domain host instead of setting the name servers to ihost I could just point the A record to ihost and point the MX elsewhere.

 Alternatively, I could backup the DNN database and restore it onto another hosted domain and remove the domain alias and DNN alias.

 Would these work, which is better or do you have any other suggestion.

Your best bet is to "clone" your DNN installation. We can perform this service for you, I believe we charge $25 one time fee to cover administrative time.

The DNN cloning process creates two identical copies of your database and file system for each cloned copy on its own hosted domain. Then our administrator removes appropriate domain aliases, updates connection strings, runs few database optimization scripts, etc. This will effectively split your DNN portals between two or more installations.

That sounds great - I'm up to my limit of 3 domains on my developer package so if I raise a ticket could you bill me for this work plus the difference to upgrade to professional?
