In this session, learn what happens in a MySQL 5.7-to-MySQL 8.0 upgrade. Discover how the upgrade precheck tool can help you prepare for your upgrade by identifying old issues in your database and collecting 5.7 metadata and re-establishing it in the uniformly stored MySQL 8.0 data dictionary. Other topics covered include upgrading from 8.0 and onward, going for an automated upgrade experience, and why an automated downgrade is challenging.
