No, you should NOT use importDump.php. You only have to import the database into MySQL. The pages and all the old wiki content will come when you import the database. They are there after you have imported the database into MySQL. That you used importDump on that database can cause problems in the future and that is what I want to save you from.

I want that:

On the new MySQL server, throw the updated DB away. Instead, put the backup of the old DB in place. The one, that has not been updated.

You can look into the DB with phpmyadmin if you have that (easy to use, nice GUI) or with MySQL on the command line:

mysql -u [user] -h [host] -p[password] use actual-wiki-db SELECT COUNT(*) FROM page SELECT COUNT(*) FROM text
