I have a installation of Kirby 1 that needs to be updated to Kirby 3, so now my question would be should I update from Version 1 to 2 and then to 3 or can I go from 1 to 3 without problems?
I don’t think it would make sense to go the intermediate step via Kirby 2. Depending on the complexity of the project it will be more than just “updating”, anyway.
