Question

Hi We have a number of flows that are running on Prefect 0 14 22 I am wondering if I can progressively upgrade them to 1 2 If I run a 1 2 agent will it work with flows written using an older version of Prefect I know it s a weird question to ask when 2 0 just went GA slightly smiling face

Anna Geller · Answer

Indeed smile I would encourage you to start slowly migrating to 2 0 instead and skip the 1 0 version I think there is very little benefit for you to migrate to 1 2 atm but it s up to your judgment to decide based on your situation I can only recommend
