Test it
Using "sandbox-migrate-to-next". Review this stable Sandbox project for SDK 1.0 migration.
Expected outcome:
Migration report: transport settings and two session APIs require removal. Three command sites need process handles. Production rollout approval remains pending.
Using "sandbox-migrate-to-next". Migrate command execution and validate the result.
Expected outcome:
- Converted string commands to explicit argv process launches.
- Added output collection and completion waits.
- Type checking and process smoke tests passed.
Using "sandbox-migrate-to-next". Prepare the migrated application for production.
Expected outcome:
Staging validation passed with matching preview versions. Immediate rollout can interrupt active work, so production deployment is awaiting explicit approval.

Skillstore Score
Why this score Evidence Confidence: MediumWhat You Can Build
Upgrade an Existing Application
Audit and migrate a stable Sandbox application to the SDK 1.0 preview.
Prepare a Production Cutover
Coordinate matching Worker and container versions, staging checks, and immediate rollout.
Review Migration Readiness
Identify deprecated APIs, incompatible process assumptions, and unresolved deployment decisions.
Try These Prompts
Review this project for migration from stable Cloudflare Sandbox to SDK 1.0 preview. List required changes and decisions before editing.
Migrate this Sandbox project to @cloudflare/sandbox@next. Update package, image, APIs, and tests. Stop before any production deployment.
Replace stable process, session, and terminal APIs with preview equivalents. Preserve behavior and validate command completion, timeouts, and cleanup.
Audit the full migration, verify matching preview versions, test staging, and present production risks. Deploy only after I approve immediate container rollout.
Best Practices
- Keep the Worker package and container image on the same preview version.
- Use installed preview types and current Cloudflare migration documentation.
- Validate in staging and obtain explicit approval before immediate production rollout.
Avoid
- Do not mix stable and preview control protocols during deployment.
- Do not treat process creation as command completion.
- Do not place live secrets in Sandbox environment variables.
