+# Pages to Workers Migration Guide
+
+## Background
+
+Cloudflare Pages does NOT support scheduled tasks (cron jobs). This project requires hourly syncing, so we migrated to Cloudflare Workers.
+
+## Setting Up Redirects
+
+To maintain backwards compatibility, configure the old Pages deployments to redirect to Workers.
+
+### For Mainnet Pages Project
+
+Create `_redirects` file in the Pages project root:
+
+```
+/api/*  https://validators-api-main.workers.dev/api/:splat  301
+/*      https://validators-api-main.workers.dev/:splat       301
+```
+
+Deploy this file to `validators-api-mainnet` Pages project.
+
+### For Testnet Pages Project
+
+Create `_redirects` file in the Pages project root:
+
+```
+/api/*  https://validators-api-test.workers.dev/api/:splat  301
+/*      https://validators-api-test.workers.dev/:splat       301
+```
+
+Deploy this file to `validators-api-testnet` Pages project.
+
+### Alternative: Dashboard Configuration
+
+Go to Cloudflare Dashboard → Pages → [Project] → Rules → Redirects:
+
+**Mainnet:**
+
+- Source: `/*` → Destination: `https://validators-api-main.workers.dev/$1` (301)
+
+**Testnet:**
+
+- Source: `/*` → Destination: `https://validators-api-test.workers.dev/$1` (301)
+
+## Verification
+
+Test redirects work:
+
+```bash
+curl -I https://validators-api-mainnet.pages.dev/api/v1/status
+# Should return 301 redirect to validators-api-main.workers.dev
+
+curl -I https://validators-api-testnet.pages.dev/api/v1/status
+# Should return 301 redirect to validators-api-test.workers.dev
+```
+
+## Timeline
+
+1. Verify Workers fully operational
+2. Deploy redirects to Pages projects
+3. Monitor for 1-2 weeks
+4. (Optional) Deprecate .pages.dev URLs and add custom domain

+### Deployment Migration
+
+Migrated from Cloudflare Pages to Workers for cron job support.
+
+**Old URLs (redirect to Workers):**
+
+- `validators-api-mainnet.pages.dev` → `validators-api-main.workers.dev`
+- `validators-api-testnet.pages.dev` → `validators-api-test.workers.dev`
+
+Setup redirects per [MIGRATION.md](./MIGRATION.md).

 **Write operations to `main` are restricted**, only via PR.
