I have an older MySQL which runs fine with v5.6.22 MySQL.
After upgrading to MySQL v5.7.9 I detected some incompatibilities.

So I have to convert the old DB to the new table and data structures.

How do I do this in detail?

Simply entering:

mysql_upgrade

does not work.

Webpage
https://dev.mysql.com/doc/refman/5.7...us-series.html
is only a general overview.

So how do the commands look like in detail for the system tables and e.g. a database "foobar"?

Thanks
Peter
