@ck7007 I'd love to checkout the toolkit aswell & thanks for sharing this strategy. 

I'm curious, is this a typical migration to Unity Catalog? ☺️.

Also, with it taking 3 weeks, there must be some chance of data not being the "latest"? 🤔. Curious if that's the benefit of the downtime is that you can get all the latest over?

All the best,
