Short answer: No—there isn’t a published EOL date or sunset timeframe for Prefect 2.x. Details and references: - Prefect Cloud compatibility: “Prefect Cloud targets compatibility with all versions of Prefect clients.” See docs: Client compatibility and versioning - Deprecation policy (general): Deprecated features are retained for at least 3 minor versions or 6 months, whichever is longer. Same page: Deprecation policy - Migration guidance (optional, no forced timeline): Upgrade to Prefect 3 If you need a formal support commitment or timeline (e.g., for compliance), I can loop in our team to provide an official statement.
