I think it ultimately depends on the specific requirements of the organization and the data being updated.

Placing old data in new fields can also be helpful for archiving purposes.

I disagree, removing the data source from production could lead to loss of important historical data.

I believe keeping only the most recent data is also important to avoid clutter and confusion.

I think removing the data source from production is not the best option. We might still need historical data.

Ooh, I like the sound of option C - creating a codebook to document field changes. That's a great way to ensure transparency and make it easier to understand the data over time.

You know, I'm kind of surprised that 'removing the data source from production' is even an option. That's like going nuclear on the problem! Let's keep things sane and go with the codebook approach.

Yeah, I was thinking the same thing. Option B, keeping only the most recent data, also doesn't seem like a great idea. We could be losing valuable historical information that way.

Haha, I can already picture the frantic emails and Slack messages if we removed the data source from production. 'Guys, where did all our data go?!' That's a hard pass from me.

I agree. Removing the data source from production (option D) seems like a drastic measure that could cause major disruptions. That's definitely not a best practice in my opinion.

Exactly, Candida! Keeping the historical data is crucial, and the codebook will be a lifesaver. I can just imagine the chaos if we started deleting old data. 'Wait, where did that crucial piece of information go?' Nope, not for me.

This question seems to be testing our understanding of best practices when updating legacy data sources. I think the key here is to maintain data integrity and traceability.

Placing old data in new fields? That just sounds like a recipe for confusion. And keeping only the most recent data? What if we need to reference historical information? Nah, the codebook is the way to go.

I agree, the codebook option seems like the most thorough approach. Plus, it'll make it easier for future developers to understand the data and its history. I'm not a fan of just removing the data source from production - that feels like we're sweeping the problem under the rug.

Hmm, this is a tricky one. Updating legacy data sources can be a real headache, but I think creating a codebook to document field changes is definitely the way to go. That way, we can keep track of what's changing and ensure consistency across the system.
