What would be the safest way to update from such an old Version to the latest one?
Would you want to keep your current profiles or not?
Not quite sure.
What would I have to do, if i would like to keep them?
And what, if I don´t want to keep them?
you need to export them one-by-one to separate ini files. Then you would update to 2021.9 or any later version. Then you would create your profiles into Paddock cloud (after making a login there) and in the edit FFB dialog there would be import button to import. Or if you don’t want to use the Paddock cloud, you can use the offline profiles section in the latest releases and import the profile settings in similar fashion there.
Thx Mika, and if i dont want to Export any profile i can install the latest driver/firmware, without installing an inbetween version?
yes, you can just get the latest version.
