Application migrations often stall because rebuilding deployment pipelines and environment setups takes months of tedious work. Your application code is rarely the problem, but rebuilding the surrounding infrastructure is a massive headache.
Here is how you can simplify the process:
- Declare your runtimes, services, and routes once in a single configuration file stored in your repository.
- Push a Git branch to automatically launch an isolated environment for testing.
- Sync real production data into your branch to validate changes safely before merging.
- Keep your existing application logic, CLI tools, and CI pipelines intact without refactoring.
Testing happens on a dedicated branch, so you never have to test in production or risk live site downtime.
