The InnoDB engine is superior. There is no reason to run MyISAM anymore. Here is a Bash script that will convert all tables, that can be converted, to InnoDB. If you do not have access to a script shell, you can do the same using phpMyAdmin or other MySQL management tools. Be sure to take a backup of the database before running this script.
