Identifying Jenkins Version from Logs

You see this line in Jenkins startup logs: 'Jenkins ver. 2.387 (weekly) started'. What does this indicate about the Jenkins version?

A It is an unsupported version

B It is a beta version

C It is a Long-Term Support (LTS) version

Managing Jenkins Upgrades Safely

What is the best practice when upgrading Jenkins from an LTS version to a newer LTS version?

A Skip intermediate LTS versions and upgrade to the latest weekly release

B Upgrade directly on the production server without backup

C Test the upgrade on a staging server and backup before upgrading production

D Uninstall Jenkins and install the new version fresh

💡 Hint

Think about safety and minimizing downtime.

Testing upgrades on a staging server and backing up production data before upgrading ensures stability and quick recovery if issues arise.
