Although this method of handling foreign key constraints is provided so that the database administrator can disable the tool’s built-in functionality if desired, a warning and confirmation request when using alter-foreign-keys-method “none” has been added to warn users when using this option.
Percona Toolkit is free and open-source. Details of the release can be found in the release notes and the 2.2.9 milestone at Launchpad. Bugs can be reported on the Percona Toolkit launchpad bug tracker.
