dasini.net – Diary of a MySQL expert

Since 8.0.16, MySQL Server supports a –validate-config option that enables the startup configuration to be checked for problems without running the server in normal operational mode.
–validate-config can be used any time, but is particularly useful after an upgrade, to check whether any options previously used with the older server are considered by the upgraded server to be deprecated or obsolete.
