+**Date:** September 6, 2025  
+**Migration:** DNSimple → Cloudflare  
+**Status:** ✅ COMPLETED
+
+## Migration Overview
+
+Successfully migrated hackclub.com DNS from DNSimple to Cloudflare using OctoDNS.
+
+### Key Changes Made
+
+1. **DNS Provider Migration**
+   - Migrated 1,154 DNS records from DNSimple to Cloudflare
+   - Upgraded to Cloudflare Pro plan (3,500 record limit)
+   - Updated nameservers to Cloudflare
+
+2. **OctoDNS Modernization**
+   - Upgraded from OctoDNS 0.9.10 → 1.13.0
+   - Updated provider class names for compatibility
+   - Added octodns-cloudflare and octodns-dnsimple packages
+
+3. **DNS Record Optimizations**
+   - Converted 14 non-root ALIAS records to CNAME records
+   - Fixed 18 CNAME conflicts by removing conflicting records
+   - Lowered TTLs to 300 seconds for faster propagation
+   - Optimized SPF record from 13 → 7 lookups (under 10 limit)
+
+4. **Cloudflare Features**
+   - Configured production-ready settings (retry logic, pagination)
+   - Enabled proxy for ai.hackclub.com (orange cloud)
+   - Set all other domains to DNS-only (grey cloud)
+
+## Production Configuration
+
+### GitHub Actions Requirements
+
+The following secrets must be configured in GitHub repository settings:
+
+```
+CLOUDFLARE_TOKEN=your_cloudflare_api_token
+```
+
+The token requires these permissions:
+- Zone:Read
+- DNS:Read  
+- DNS:Edit
+- Page Rules:Edit
+
+### Provider Configuration
+
+Updated config/production.yaml to use:
+- Primary target: Cloudflare (was DNSimple)
+- Provider class: octodns_cloudflare.CloudflareProvider
+- Plan type: pro
+- Enhanced reliability settings
+
+## Current Status
+
+✅ All DNS records migrated successfully  
+✅ Nameservers switched to Cloudflare  
+✅ SPF record optimized and compliant  
+✅ All services working normally  
+✅ Email routing functional  
+
+## Rollback Plan (if needed)
+
+If issues arise, rollback steps:
+1. Change nameservers back to DNSimple
+2. Revert config/production.yaml targets to dnsimple
+3. Deploy via GitHub Actions
+
+## Files Modified
+
+- `hackclub.com.yaml`: DNS records with optimizations
+- `config/production.yaml`: Updated for Cloudflare
+- `.github/workflows/deploy.yml`: Updated OctoDNS version and packages
+
+## Migration Tools
+
+All migration tools and test files moved to `migration-tools/` directory for reference.
