Which settings are kept? Seems like server config, rules, custom properties would all be lost.

Hello @mgranillo!

Uninstalling Qlik Sense like this retains the database as well. The database stores settings, such as security rules, properties on services, user allocations, etc...

We do recommend taking a backup of the DB regardless, which could be restored if necessary.

When re-installing, the following will be displayed:

Proceeding with the installation will prompt to re-use the existing local DB and require a login:

Will this method also keep the license of the system?

I would need to do a re-install as our new license key is now LEF (instead of signed license) and therefore cannot be activated without re-installation.
So I wondered if this method would work in the case of switching from singed license to LEF.

Hello @t_witzgall 

To clarify before I give this a test: Do you want to switch from the Singled License Key to a LEF key? This would require a complete uninstall with the removal of the database.

Yes - that is the switch I want to do. I'm currently searching for a timesaving way but it seems there is none.
(As backup and restore the database would also not work then ..)
