However im now getting class cannot be found error?
Fatal error: Class 'Doctrine\Bundle\DoctrineMigrationsBundle\DoctrineMigrationsBundle' not found in /media/sf_projects/symBlog/app/AppKernel.php on line 24
However im not sure why im getting it the path looks correct to me see screenshot below?

Found it the register path in the new version is
new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),
