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:
- connect the existing application
- run both environments in parallel
- cut traffic over when the new path is proven
- connect the existing application

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.
