Data and Code migration are two very different areas.
For data: Using representative data for development is important but using full volume production data for this is often not a good idea because A) full volumes slow down development (i.e. long running jobs) and B) PII/sensitive data should not be used in a Dev environment with normally much less security applied.
For DIS "code"/SAS Metadata
The process for moving data from one environment to another should be the similar so use what has been used to get DIS jobs into Prod in first place (if that is already a successful and established process).
