プライム戦略 has launched ‘KUSANAGI SafeUpgrade.’ This key feature in KUSANAGI Security Edition keeps web servers updated. It does this without causing service disruptions. The feature supports major version upgrades of nginx. This web server powers over 33% of the world’s websites. About 96% of these run on versions that no longer get security updates.
SafeUpgrade sets up a parallel test environment on the same server. It starts checks and only activates the updated version if they succeed. This process cuts downtime and lowers the chances of failure. If an issue arises, the system defaults to the previous version. This allows for a smooth rollback.

Future releases will add support for PHP upgrades and include more security features. This will increase the platform’s ability to maintain the system safely and continuously.
