A sequenced approach for teams sitting on a working system that has become hard to change.
Rewrites feel clean and often stall. If the current Django app still holds the business, we usually wrap, extract, and replace in slices: tests around the core, a new UI on the same APIs, then module-by-module rebuilds.
The first modernisation win is deploy confidence — CI, staging that looks like production, and migrations that can roll forward. Without that, a rewrite is just a new way to be afraid of Friday deploys.
We only recommend a greenfield rebuild when the domain has changed more than the code, or when the runtime is no longer supportable. Otherwise, sequenced modernization keeps customers online.
