A really well-structured and practical guide! 🚀 You’ve done a great job covering the real-world considerations that often get missed when planning legacy database modernization.
What stood out to me most was the focus on hidden dependencies, data quality, and rollback planning. 🔍 These areas can have a huge impact on migration success, especially when dealing with business-critical systems. I also liked how you broke down rehost, replatform, refactor, and rebuild, making it easier to understand which approach fits different situations.
The emphasis on testing, security, and post-migration optimization makes this much more than just a migration guide. 👏 A valuable resource for engineers and technology leaders planning their modernization journey.
