@Marvin Is it possible to call a deployment using Prefect 2.x while the flow that calls the deployment is running Prefect 3.x?

Yes, it is possible to call a deployment using Prefect 2.x within a flow running Prefect 3.x. Prefect allows you to schedule and run existing deployments programmatically using the

run_deployment

function in Prefect 2.x. This function is designed to be used within your Python flow code to manage the execution of other deployments. In Prefect 3.x, the general concept of deployments remains and they act as configuration entities for when, where, and how flows should run. You can interact with these using similar mechanisms, although Prefect 3.x may offer additional features or changes in syntax reflecting its updates. For specific implementation guidance: - In Prefect 2.x, you can use

from prefect.deployments import run_deployment

to call an existing deployment from within your flow. - In Prefect 3.x, the same principles apply for running flows via deployments, but you may need to reference updated constructs or utilities available in this version. This typically involves using newly introduced features or syntax adjustments, which would be documented in the latest Prefect 3.x documentation. You can find more detailed examples and guidance in the Prefect documentation: - Prefect 2.x documentation on Deployments - Prefect 3.x documentation on Deployments
