My solution - launch your mysql shell and paste:

SELECT CONCAT('ALTER TABLE ',CONCAT(TABLE_SCHEMA,'.',TABLE_NAME),'     
ENGINE=InnoDB;') 
FROM INFORMATION_SCHEMA.TABLES
WHERE ENGINE='MyISAM'
AND TABLE_SCHEMA NOT IN ('MYSQL','INFORMATION_SCHEMA','PERFORMANCE_SCHEMA','SYS')
INTO OUTFILE '/tmp/mysql.conversions';
SOURCE /tmp/mysql.conversions;
