Upgrading Sink

Before upgrading

1. Review the upstream release notes.
2. Preserve your Cloudflare bindings, secrets, and environment settings.
3. If R2 is configured, consider creating a manual link snapshot.

Upgrade a D1 deployment

1. Use GitHub to sync your fork with the upstream master branch. Resolve any conflicts caused by your own changes.
2. Redeploy the updated master branch through Workers Builds or Pages.
3. Wait for the deployment to finish.

Upgrade a legacy KV-only deployment

If the existing instance stored links only in KV, preserve the original KV data in Cloudflare and follow the separate KV-to-D1 migration guide.

Verify

• Open the dashboard and confirm that sign-in works.
• Create, open, edit, and delete a test link.
• Check analytics and other optional features that you have enabled.
