Kirby 3.5 Migration

I want to migrate vom Kirby 3.4 to 3.5 and already got the builder plugin installed. Some while back there was an excellent migration guide uploaded to the kirby website:

I cannot find those guides. I guess I’ll be able to migrate without those guides, still they were helpful and I cannot really understand, why those were moved or deleted. Does anyone know the new URLs?

Thank you very much :slight_smile:
