I like the idea and think it looks great, but I'm requesting a review from @calreynolds or @dustinvannoy-db, as it's entirely new and we don't have migration skills right now.

We will get back to you! We're debating whether we want to include anything third-party or not

My content feedback would be: I think we can trim this generally!

Also, can you adjust the file structures to be similar to how we do spark-declarative-pipelines? The more uniform, the easier for the llm to digest

Thank you for the feedback. Will follow up on this and let you know when I am done. Also it is more of a PowerBI to Databricks migration, but because of the naming convention it is confusing. Let me know if you want me to change it.
