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 🙂

Indeed 😄 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
there are some things that existed in 0.14.22 but no longer exist in 1.0 like environments, API tokens https://docs-v1.prefect.io/orchestration/execution/custom_environment.html

Thanks, Anna. We have a lot going on and need to put this new flow in prod. If I use the 1.2 agent, it it be able to start the older flows? Thanks

can't say for sure, it depends on many factors
