Magento Certified Developer GuideCategory: 4. DatabaseHow can you implement a rollback in Magento
Manish Prakash Staff asked 5 years ago

Magento doesn’t have full support for rollback, uninstall yet.
When the db version of module is more than the config, rollback function is triggered in ‘core/resource_setup’ model.

But we cannot specify any rollback files, as this is not implemented yet by magento.
