MySQL 8.3 Reference Manual  /  ...  /  mysql_upgrade — Deprecated; Performs No Tasks and Exits with Status 0

6.4.5 mysql_upgrade — Deprecated; Performs No Tasks and Exits with Status 0

Note

The MySQL server performs the upgrade tasks previously handled by mysql_upgrade (for details, see Section 3.4, “What the MySQL Upgrade Process Upgrades”). Consequently, mysql_upgrade is unneeded and is deprecated; expect it to be removed in a future version of MySQL. Because mysql_upgrade no longer performs upgrade tasks, it exits with status 0 unconditionally.
