Hi, are there any depreciation dates for Prefect 1 and Prefect 2?

Hi Angelika! Prefect 1 is no longer under active development, and Prefect 2 will be supported for the foreseeable future.

is there a plan to turn off prefect 1 cloud?

yea -- our public date for decommissioning Cloud 1 is long past, so now we work directly with any remaining teams to plan out individual migration targets. Please let me know if there's anything in particular I can do to help you migrate!
