I see two possible problems:

You say you have run the setup "with a MySQL database". Did you also import your old database into it? If you did not import your data, then it is clear that MediaWiki does not show it.

On the new host, do you have new MySQL credentials? Nearly always that is the case. Adjust the data in LocalSettings.php accordingly!
