The basic idea should work-- change the prefix in both wp-config.php and in the database itself. What isn't covered would be cases where the prefix is used in other contexts such as when used as part of a "meta" key. Those cases you would need to trace down one by one.
You could also have trouble it the prefix has been hard-coded into anything, but ...
