Yes, potentially there are "gotchcas". It all depends on your current MySQL server version and the version you are upgrading to.
Assuming you are upgrading 3.23 to 4.0, what I would do is look at the official documentation regarding upgrades from exactly this scenario: http://dev.mysql.com/doc/refman/4.1/en/upgrading-from-3-23.html I think you'll find the upgrade pretty painless from a data point of view, but you will need to heed the changes to the GRANT tables.
