Hi Art,
Here is a link to our licensing and upgrades page that will answer your questions about changing the domain for your license key:
http://www.smith-consulting.com/forums/licensingandupgrades.aspx
Other items to consider when changing the domain name on a dnn site that is already built:
- Change your dns for the new domain name to point to the ip address of the site
- Is you are using iis host headers then you would need to change the domain name in the host headers section of iis.
- If you have a dedicated ip address then you would just need to change the dns as described in item 1 above
- If you have any hard coded links in the site that reference the full url with the domain name those would need to be changed to relative links
- Change your SMTP settings to reference the new domain name if needed
- Re issue your Smith Cart license key for your new domain name
- Change any google analytics javascript you may have
- Change any google xml sitemaps you may have
Thats all I can think of for now!
