mysql: Too long to run

Sorry for my bad English.
I hope you understand

We are updating our piwik(2.17.1) to the most stable version (4.4.1).
We started the update via the browser, but it was not possible.
We went to update via command line:

  • php /var/www/html/piwik/console core:update
    starts the update, but when it runs the command:

ALTER TABLE piwik_log_visit CHANGE idvisit idvisit BIGINT(10) UNSIGNED NOT NULL AUTO_INCREMENT;

it spends many hours running without any response.

Settings:

application:

  • Red Hat Enterprise Linux Server release 6.10
  • PHP 7.3.25 (cli) (built: Nov 24 2020 14:31:55)
  • apache
