I'm going to be changing the domain name of one of my sites. I'll use 301 redirects.
One thing that I can't figure out is how to preserve all the comments that users have made on the page through Facebook. We use the Facebook developer comment API to allow comments on our pages.
It appears that when I change the URL of my page, the comments on the page disappear. Is there any way to let facebook know that this URL is changing and that comments should be moved over?
