What are three critical items a system administrator should back up before upgrading Qlik Sense Enterprise?

A system administrator must prioritize specific items for backup before upgrading Qlik Sense Enterprise in order to ensure a smooth transition and safeguard against potential issues. One of the critical items is the Qlik Sense certificates. These certificates are essential for securing communication between different components of the Qlik Sense environment and ensuring that all interactions are authenticated and encrypted. Without these certificates, the system may face significant risks concerning data security and integrity, and the upgrade process could result in failed connections or lost access to resources.

While other options may also appear essential, the Qlik Sense certificates hold unique importance due to their role in maintaining security and connectivity within the system. Backing up these certificates enables the admin to restore them if needed, maintaining the secure framework of the Qlik Sense deployment.
