how should I do an upgrade of qliksense desktop ?
most important is to keep all existing apps.
just download the newest Version and install it, Backups of your Apps are automatically made (C:\Users\"Username"\Documents\Qlik\Sense\AppsBackup)
If you're not comfortable with this, just copy your Apps- and Extension-Folder to another Folder
As Christoph said.
All your app should be compatible with new version.
Sometimes some extension may not work but you need to test this yourself
