Freezing Legacy Accounts

Today we are announcing that legacy Prefect Cloud 1 accounts will be frozen for some users starting May 15th 2023. This means that your account and tenant will become read-only, and your flows & tasks will no longer run. Note that this only pertains to Starter and Standard users of Prefect Cloud 1 on monthly plans, available at Enterprise users or those with annual agreements are not impacted by this announcement.

Upgrade Help

Since the release of Prefect 2 in October 2021, we have been working towards making a better, faster and more flexible orchestration platform. Today, Prefect 2 and Prefect Cloud 2 have achieved those goals.

Prefect Cloud 2 is available with a free tier and a simple pricing model based on users & workspaces. To help our remaining users as they transition, we are providing migration support to all users via written guides, videos and help from real Prefect engineers. To get migration support, visit

As always, you can reach us directly in our community Slack, booking a time with a product advocate, or by emailing us at
