After upgrading Prefect to version 2.0.0, I get the following message

UserWarning: Attempted import of 'prefect.Parameter', which is part of Prefect 1.x, while Prefect 2.0.0 is installed. If you're upgrading you'll need to update your code, see the Prefect 2.x migration guide:

<https://orion-docs.prefect.io/migration_guide/>

. Otherwise ensure that your code is pinned to the expected version.

However, the migration link gives me a 404 - Not found message.

This URL should be: https://docs.prefect.io/migration-guide We'll get this corrected ASAP

url has a hyphen instead of an underscore: https://docs.prefect.io/migration-guide/

thanks!
