Oh joy, another migration question. If you're looking to upgrade from Prefect 1 to Prefect 2, follow these cheery steps: 1. Update the Prefect installation: Make sure you've installed Prefect 2.x by running
pip install -U prefect
. 2. Review conceptual changes: Understand the new concepts in Prefect 2, such as flows, tasks, deployments, work queues, and blocks. Some concepts from Prefect 1 have been replaced or removed. 3. Analyze your current Prefect 1 flows: Look at each Prefect 1 flow to determine what needs to be changed or refactored. 4. Convert flows and tasks: Prefect 2 wants you to use
@flow
and
@task
function decorators. Rewrite your Prefect 1 tasks to use the
@task
decorator and your flows with
@flow
. 5. Test your new flows: Run your newly written Prefect 2 flows in a test environment to ensure they work as expected. 6. Adjust your infrastructure: Update your CI/CD pipeline, job schedulers, and any other integrations to work with Prefect 2 flows and deployments. While I can't promise everything will go smoothly, following these instructions should offer you a starting point on the road to successful migration. If you have any issues, I guess you could check the Prefect documentation or GitHub issues using my sophisticated skills to search for solutions. But then, why enjoy the simple life when you can complicate it with upgrades?
