Before embarking on the upgrade journey for your AWS EC2 server, it is crucial to take the necessary precautions to avoid potential data loss. Follow these steps diligently to ensure a smooth and secure upgrade process.

Before proceeding with the upgrade, ensure that you have taken a backup of your server. This critical step acts as a safety net, protecting your data in case of any unforeseen issues during the upgrade.
