Rehost vs Replatform vs Refactor: A Decision Framework for Modernization

A fast decision tree to pick show-your-work modernization paths that map to business outcomes.

Rehost, replatform, refactor—pick with intent

Modernization decisions are often made emotionally (“we should refactor everything”). A better approach is a simple decision framework based on risk, timeline, and the business outcome you need.

The quick decision tree

  • Rehost when you need speed and stability (and you’ll optimize later).
  • Replatform when you can make targeted platform changes (managed DB, containerization) for meaningful gains.
  • Refactor when the architecture blocks mission outcomes (scale, resiliency, security) and you can invest time.

Questions that drive the right choice

  • What’s the deadline and what happens if we miss it?
  • Where is the operational pain (deployments, scaling, incidents)?
  • What compliance constraints apply (data, logging, access control)?
  • Can we isolate the risky parts and modernize incrementally?

A pragmatic path for SMBs

  1. Rehost to establish cloud foundations and stop the bleeding.
  2. Replatform the most painful dependencies (databases, queues, CI/CD).
  3. Refactor only where it drives clear outcomes.

We can help you map apps to the right strategy and build a modernization backlog that ships value every sprint.
