Upgrade/Downgrade website versions of WordPress with wp-cli
You can use wp-cli to upgrade or downgrade to particular versions or releases of WordPress.
See the installed version of current WordPress
wp core version
or with more info:
wp core version --extra
Update to latest version of WordPress
wp core update
Update to specific version of WordPress
wp core update --version=5.5.3
Install or downgrade WordPress version
wp core update --version=5.5.3 --force
Switch to a locale version (Australia used below)
wp core update --locale=au
Update Error
If you get the Error: Another update is currently in progress.
You can clear that with:
wp option delete core_updater.lock
Then try again.
Couple more refs on wp-cli for plugins, domain URLs and installations.
Thanks for this article it has really helped understanding that you can use WP-CLI within the downgrade plugin and achieve the same result.
Kind regards,
