+# Production Migration Test Runbook
+
+## Objective
+Validate full disaster recovery capability by restoring production to a new
+Linode, cutting over DNS, and confirming the site runs cleanly on fresh
+infrastructure.
+
+## Pre-Migration (Day Before)
+- [ ] Post maintenance notice on Instagram (Jenny)
+- [ ] Add site banner or maintenance page notification
+- [ ] Confirm Linode Backups are enabled on production
+- [ ] Verify Cloudflare dashboard access
+- [ ] Have SSH keys ready for new server access
+- [ ] Notify Jenny of maintenance window and estimated downtime (30-60 min)
+
+## Migration Steps (Early Morning)
+
+### 1. Final Production Snapshot
+- [ ] Log into Linode dashboard
+- [ ] Navigate to production Linode → Backups tab
+- [ ] Take manual snapshot, label: `pre-migration-YYYY-MM-DD`
+- [ ] Wait for snapshot to complete (watch progress in dashboard)
+
+### 2. Spin Up New Linode from Snapshot
+- [ ] Linode dashboard → Create → From Backup
+- [ ] Select the snapshot just taken
+- [ ] Choose same or equivalent plan (2GB Linode)
+- [ ] Same region as current production
+- [ ] Note the new server's IP address
+- [ ] Wait for provisioning to complete
+
+### 3. Verify New Server
+- [ ] SSH into new server using noted IP
+- [ ] Run `docker ps --format "table {{.Names}}\t{{.Status}}"` — confirm
+all containers are running
+- [ ] Check WordPress responds: `curl -H "Host: plantbasedsoutherner.com"
+http://localhost:80`
+- [ ] Verify MySQL is healthy: `docker exec mysql-container mysqladmin ping`
+- [ ] Spot check wp-content files exist in the WordPress volume
+
+### 4. DNS Cutover
+- [ ] Log into Cloudflare dashboard
+- [ ] Navigate to plantbasedsoutherner.com DNS settings
+- [ ] Update A record to new Linode IP address
+- [ ] Cloudflare proxied traffic should cut over within minutes
+- [ ] Verify: browse to https://plantbasedsoutherner.com from phone
+- [ ] Check multiple pages — homepage, a recipe, member login
+- [ ] Test PBS-API health endpoint
+- [ ] Verify n8n is accessible and workflows are intact
+
+### 5. Post-Cutover Validation
+- [ ] Check Uptime Kuma monitors are green
+- [ ] Verify Portainer accessible
+- [ ] Confirm SSL certificate is valid (green lock)
+- [ ] Test Instagram automation — trigger a test comment if possible
+- [ ] Check Google Chat alerts are still routing
+
+## Decision Point
+
+After validation, choose one:
+
+**Option A: Keep New Server**
+- [ ] Update Linode dashboard labels/tags
+- [ ] Update any hardcoded IPs in Ansible inventory
+- [ ] Run updated Ansible against new server to layer staging changes
+- [ ] Destroy or archive the old production Linode
+- [ ] Update SSH config with new server IP
+
+**Option B: Revert to Original**
+- [ ] Flip Cloudflare DNS back to original Linode IP
+- [ ] Verify site works on original server
+- [ ] Destroy the temporary test Linode
+- [ ] Document any issues found for future reference
+
+## Rollback Plan
+If anything goes wrong at any step:
+1. Flip Cloudflare DNS back to original production IP
+2. Original server is untouched and still running
+3. Destroy the test Linode
+4. Site downtime should be under 30 minutes total
+
+## Post-Migration
+- [ ] Remove maintenance notice / site banner
+- [ ] Post on Instagram that site is back up
+- [ ] Document outcome and any lessons learned
+- [ ] Update Tech Wiki with any new findings
+
+## Key Details
+- **Production domain:** plantbasedsoutherner.com
+- **DNS provider:** Cloudflare (proxied)
+- **Current hosting:** Linode 2GB
+- **Estimated downtime:** 30-60 minutes
+- **Best window:** Early morning, low traffic
+
+## Lessons Learned
+*(Fill in after completing the test)*
