When reinstalling 3CX, can the key-FQDN mapping be unbound by the user?

Reinstalling 3CX involves various considerations regarding the configuration and key-FQDN mapping. The correct answer indicates that users have the ability to unbind the key-FQDN mapping on their own. This is significant because unbinding allows for flexibility in managing system configurations and adapting the existing settings to the new installation.

Users often need to change or update their setup, such as modifying their hosts or transitioning to different domains, and the ability to unbind the mapping empowers them to do so without reliance on external support or constraints. Additionally, it streamlines the reinstallation process, ensuring that users can take control of their system configurations effectively.

In contrast, the other options imply limitations on user capability, which may not align with the autonomy that 3CX aims to provide in managing installations and configurations.
