Here's a guide on proper procedures for updating qlikview: Upgrade and Migration ‒ QlikView . Essentially backup your Qlikview directory, stop all services, perform install, reboot server. You'll need the windows account the current Qlikview services are running under. If you are worried about the Qlikview developer tool messing up your current dashboards, I would make a backup. I noticed that the dashboards will still open in the old QV11 even if they have been opened and saved with QV12.
Ok, this is great information. I think I didn't realize that I have to upgrade the Qlikivew WebServer in addition to Qlikview Desktop which was leading to my confusion.
For the backups, do I have to turn on another server, or can I just back up to another drive on the same server and do everything from the same server?
How did you get the dashboard to open with 12 even if they were open and saved with upgraded version?
