Migrate as easily as you deploy
Straightforward migration. Switch in hours or days, not a multi-month project.
1
Connect your Heroku account
We'll import your existing apps, environment variables, and add-on configuration automatically.
2
Review your build config
Build auto-detects your buildpack and environment. Review and confirm — or customise if needed.
3
Run in parallel, cut over when ready
Deploy to Build alongside Heroku. Validate, test, then switch DNS when you're confident. Zero downtime.
1
Connect your Git repository
Point Build at your existing repo. No changes to your codebase required.
2
Map your services to Build primitives
Define your runtime using your existing Buildpack or Dockerfile. Provision managed add-ons to replace databases, caches, and background services.
3
Switch when you're ready
Run Build alongside your current platform. Migrate data and shift traffic at your own pace. Switch in hours or days, not a quarter-long project.
