What it does
Migrate Cloudflare Sandbox apps from stable @cloudflare/sandbox to @cloudflare/sandbox@next (SDK 1.0 preview). Use sandbox-next for apps already on the preview.
Migrate stable → Sandbox SDK 1.0 preview (@next)
Perform the port. Follow the steps in order. Depth lives in docs, fetch the linked page when a step needs detail.
Human guide: Migrate · 1.0 preview
New projects should start on @next (sandbox-next), not this skill. Day-to-day stable work → sandbox-stable. Deprecated-API cleanup without moving to @next → 2026 deprecation guide first if needed.
Existing apps should migrate when you can, so you are ready when 1.0 becomes the stable release. Do not force production cutover without the user agreeing.
Prefer installed @next types and the migrate doc over memory.
Workflow
- Review hard rules and the replacement map
- Audit the codebase; list hits and target shapes
- Clarify with the user (cutover, bridge, Python image, unclear sites)
- Upgrade package, image, and code
- Validate
Stop after any step that needs a user decision.
