I am trying to upgrade from 4.1 to 5.1.
Your manual states I should run mysql_upgrade.
But there is no such program in our pre-compiled binary, only a man page!
$ find . -name "mysql_upgrade*"
However the on-line manual states the follows does the same thing:
$ mysqlcheck --check-upgrade --all-databases --auto-repair
Is this safe?
I only ask because the last time I tried to upgrade, MySQL core-dumped
every few minutes when an unknown user connected. So I am looking at
every incontinuity to try and work out if this is the reason.
Thanks for any help,
