I am also trying to move my site thelocalspoon.com from .com to www.ads-software.com.
I also ran in to the same issue as you (have been running in to many issues — I am beginning to wonder if this is worth the hassle!) I do not think the issue we both are facing is a wordpress issue, it is on the GoDaddy side and has to do with changing your nameservers.
Go to your GoDaddy portal to your Domain Manager (My Products –> Domains –> View Domain Manager).
Check the box for the domain name in question, then click on “Nameservers” in the top menu bar. Then “Set Nameservers”. Yours was probably like mine, set to the WordPress nameservers. Click on “I have a hosting account with these domains.” instead.
It may take up to a day or two for the changes to propogate, but then you should be able to login to the new www.ads-software.com admin panel to begin the switch.
Hope that helps — I am not done with my transition either, so no final promises…
