What is the recommended process for performing a Qlik Sense upgrade?

The recommended process for performing a Qlik Sense upgrade involves running the Qlik_Sense_Update.exe and stopping services except for the repository database. This method ensures a controlled and safe transition to the new version while minimizing potential disruptions to ongoing operations.

By stopping the services, you can prevent users from accessing the application during the upgrade, thereby avoiding any conflicts or data integrity issues that might arise if they try to use the system while it is being updated. The repository database is typically kept running to maintain the integrity of the application data and configurations during the upgrade process. This approach allows for a smoother upgrade experience and ensures that all necessary components are updated correctly without losing any critical data.

Other methods, such as deleting the old installation or using Command Prompt to run the update while disabling firewalls, pose significant risks, including the loss of existing configurations and potential security issues. Similarly, restarting the server and running the setup without proper preparation can lead to unexpected downtime and complications, making the proposed answer the most reliable and efficient choice for upgrading Qlik Sense.
