Feature Flags Migrate Strategy Workflow
Migrate from direct deployment to feature flag-controlled releases with a migration plan and team training.
Objective
Adopt feature flags for safer, more controlled deployments.
Environment
- A deployment pipeline currently using direct deployment
- A feature flag system to adopt
- Team members to train on the new workflow
Steps
1. Choose a system
Select a feature flag system that fits the team size and budget.
Expected state: A feature flag system is selected and installed.
2. Pilot with one feature
Use feature flags for one upcoming feature to validate the workflow.
Expected state: The feature flag workflow is validated with a real feature.
3. Create flag lifecycle
Define a process for creating, testing, and retiring feature flags.
Expected state: A flag lifecycle process is documented.
4. Train the team
Conduct training sessions on creating, rolling out, and cleaning up feature flags.
Expected state: All team members are trained on the feature flag workflow.
5. Update CI/CD
Integrate feature flag checks into the CI/CD pipeline for automated verification.
Expected state: The CI/CD pipeline supports feature flag workflows.
Decision points
Build or buy a flag system?
- Buy for speed
- Build for control
Buy a managed service for speed and reliability; build only if you need deep integration or have strict data residency needs.
Expected outcome
Feature flags are adopted with a documented lifecycle, trained team, and integrated CI/CD.
Verification
Create a test feature flag and verify the full lifecycle: create, roll out, ramp to 100 percent, and clean up.
Cleanup
Remove test flags after verifying the workflow; keep the feature flag system installed.
Flags decouple deploy from release
Feature flags let you deploy code safely and control who sees it, reducing deployment risk significantly.
Implementation Notes
This workflow provides a structured approach to ensure consistent results across team members and environments.
Common Pitfalls
Skipping verification steps or rushing through the process can lead to incomplete results. Always follow each step in order and verify before proceeding.
