Hi Guys,

Paul, when you did your mysql_update testing, are you sure the update
actually modified the mysql database?  If the mysql database was created
by 5.6's mysql_install_db.pl it will be skipped by mysql_update, even if
you use the --force option.

My process was to copy the data\* directory from mysql51 to my mysql56 test directory,  then run mysql_upgrade.

mysqld now starts without warnings - so I figure it did what it needed to do...

Cheers,

Paul
