Mysql upgrade

Eind 2019 heb ik een nieuwe laptop in gebruik genomen. MySQL Workbench werkte erg slecht. Ik had aanwijzingen dat mysql_upgrade kon helpen. Dat bleek tegen te vallen. Ik geloof dat het niet eens meer bestaat. Het zou een command line-routine zijn, zoals mysqldump.

mysql_upgrade -u root

The mysql_upgrade client is now deprecated. The actions executed by the upgrade client are now done by the server.
To upgrade, please start the new MySQL binary with the older data directory. Repairing user tables is done 
automatically. Restart is not required after upgrade.
The upgrade process automatically starts on running a new MySQL binary with an older data directory. To avoid 
accidental upgrades, please use the --upgrade=NONE option with the MySQL binary. The option --upgrade=FORCE is 
also provided to run the server upgrade sequence on demand.
It may be possible that the server upgrade fails due to a number of reasons. In that case, the upgrade sequence 
will run again during the next MySQL server start. If the server upgrade fails repeatedly, the server can be 
started with the --upgrade=MINIMAL option to start the server without executing the upgrade sequence, thus 
allowing users to manually rectify the problem.
