Moving off complex platforms without slowing down

A practical look at reducing migration risk while changing hosting platforms.

Most migrations fail because teams try to change everything at once.

The safer pattern is simpler:

  1. connect the existing application
  2. run both environments in parallel
  3. cut traffic over when the new path is proven
  • connect the existing application
  • run both environments in parallel
  • cut traffic over when the new path is proven

Keep the migration narrow

Treat the first migration as an operational move, not a full rewrite.

Use the same app, the same runtime assumptions, and the same release process wherever possible. Change the platform first, then improve the stack once production is stable.
