We will be upgrading the MySQL version on the Raptor and Cobra servers from MySQL 5.6 to MySQL 5.7 on Tuesday 23rd February 2020 at 23:00 GMT.
Your MySQL databases may be unavailable for up to 20 minutes while the upgrade takes place so your web-sites may show database connection errors during this time.
MySQL ‘Strict Mode’ will be disabled, this means that code that isn’t designed for MySQL 5.7 should continue to work correctly so you shouldn’t need to make any changes.
