Why all application migrations should be incremental
Aug 30, 2023

Summary
This post details incremental migration strategies, contrasting 'big bang' with 'incremental' approaches (vertical and horizontal). It highlights the trade-offs, particularly the interop effort versus risk reduction. For frontend migrations, it emphasizes the use of reverse proxies and Vercel's Edge Middleware for phased traffic migration. It also touches upon migrating from monolithic to composable architectures and the specific techniques for migrating web frontends using reverse proxies and gradual traffic shifting.
