I've seen a few threads on this subject, but they're pretty old. Thought I'd reach out and see if there's there were any developments on this subject.
We have a highly complex data structure (500+ objects, multiple dependencies), and trying to move away from developing in a full/partial sandbox, to developing in personal developer sandboxes. However, we need a small subset of data to work with. That also includes many custom settings which of course are being created empty in dev sandbox after refresh, and our code highly relies on their data (too many to try to move them to MDT, would be a long project).
We don't want to have to move every piece of half baked code to full sandbox just for testing during development, that misses the point of developing in personal sandboxes in my opinion.
Has anyone ever tried to tackle this challenge? What did you do? Any thoughts and recommendations would be highly appreciated!
