S’il n’y a que des Notebooks à transférer :

• Best option: put the notebooks in Git and reuse the Git in the new workspace as part of the CI/CD process: https://docs.databricks.com/repos/index.html
• use terraform exporter with -match flag to generate .tf scripts allowing to re-deploy jobs.

You can also rely on https://github.com/databrickslabs/migrate, but this option does not invest in your CI/CD setup, so should be considered if a one-time migration is required.
