We're migrating a site from one host to another, and want to make sure that our 'likes' travel with us.
Am I correct to think that the like counts are fetched from Facebook based on the URL of the post that's being viewed?
I ask because I'm mid-way through a migration. We're migrating a site from a '.tv' domain to a '.com' domain. Once that's ready we're going to park the '.tv' domain onto the new location and set WordPress to use '.tv' from then on. This might sound a strange way to go about things but that's another story for another day.
Right now, the old '.tv' site still shows counts of likes. But the new '.com' site shows zero likes. We thought for a while that 'like' counts would be in the database but we can't find them there and anyway that would be open to abuse, so now we're working on the assumption that when the new site's URLs are back to using '.tv' everything might fall back into place.
Is that right, or is there anything else we should do to get our like counts migrated?
Thanks in advance
