What is the correct procedure to upgrade from V14 to V15?

The correct procedure to upgrade from version 14 to version 15 involves taking a full backup of the current system before making any changes to ensure that all settings and data can be restored if necessary. This step is crucial because it allows you to safeguard important data against any potential issues that may arise during the upgrade process.

After performing the full backup, the next logical step is to uninstall the previous version (V14). This action clears the environment and prepares it for the new installation without any residual configurations or data that might conflict with the new version. Once V14 is completely uninstalled, you then proceed to install version 15. At this point, the system should be running the latest version.

Finally, restoring the backup taken from V14 is key to ensuring that any user configurations, settings, and historical data are brought into the new system. This allows users to operate seamlessly on the upgraded version without losing any previous data or configurations.

Consequently, this process encapsulates a logical and risk-mitigated approach to upgrading the software while preserving critical user data.
