Thanks for taking the time to participate in the GoDaddy Community!
First, I just wanted to let you know that if you've already added the domain in question to your server, simply pointing the domain's DNS toward your server would be enough to get your site back up. You don't really need to worry about removing it, though that is a good idea to avoid future confusion. The proper steps to change your domain on a Plesk hosting account can be found here.
I also wanted to let you know I've moved your post to the Building And Managing A Website board, as it was a better fit for the issue you were asking about.
Does anyone else in the community have thoughts on this? Please weigh in.
