If you use PowerShell for your CI/CD pipelines you may want to have a look at my DatabricksPS module which is a wrapper for the Databricks REST API.

It has dedicated cmdlets to export (e.g. from DEV) and import again (e.g. to TEST/PROD) in an automated fashion. This includes notebooks, job-definitions, cluster-definitions, secrets, ..., (and SQL objects to come soon!)
