Upgrading Sink

Before you upgrade

1. Skim the upstream release notes
2. Do not delete your Cloudflare bindings, secrets, or env vars
3. If R2 is set up, consider a manual backup

Normal upgrade (current D1 installs)

1. On GitHub, open your fork → click Sync fork to pull the latest master. If you changed files yourself, resolve conflicts first
2. In Cloudflare (Workers Builds or Pages), redeploy the updated master branch
3. Wait for the deploy to finish (database updates run as part of deploy)

Upgrading a very old install (links only in KV)

If your instance stored links only in KV (older Sink versions), keep that KV data and follow storage setup / migration.

After upgrade — quick check

• Sign in to the dashboard
• Open Dashboard → Links once (finishes storage setup if needed)
• Create, open, edit, and delete a test link
• Check analytics if you use it
