database upgrade to 2.1 from the command line (1 reply)

Hello all,
after copying the version 2.1 on the server, a webpage with a warning is shown, that large databases should run the database update from the command line:
php /var/www/<server>/htdocs/index.php -- "module=CoreUpdater"
If I run the command no change is made to the database:
"Note: this is a Dry Run"

The piwik site (http://piwik.org/docs/update/) mentions another procedure:
./path/to/piwik/console core:update

What is the correct way to upgrade the database?
Best regards
Thomas
