Important notes for large Matomo installations
If you have a large Matomo database, updates might take too long to run in the browser. In this situation, you can execute the updates from your command line:
php /var/www/html/console core:update
If you manage a high traffic Matomo server, we recommend to momentarily disable visitor Tracking and put the Matomo User Interface in maintenance mode.
FYI: these are the SQL queries and console commands that will be executed to upgrade your database to Matomo 4.2.1
