+## Migration Process
+
+### Phase 1: Pre-Migration Assessment
+1. Audited Gitea installation on Command Center
+2. Identified repository structure and size
+3. Created file manifest with MD5 checksums (140 files)
+4. Documented configuration settings
+
+### Phase 2: Backup Creation
+1. Stopped Gitea service on Command Center
+2. Created complete backup tarball
+   - `/var/lib/gitea` (data directory)
+   - `/etc/gitea` (configuration)
+   - Pre-migration manifest
+3. Verified backup integrity
+
+### Phase 3: Server-to-Server Transfer
+1. Generated SSH key on Command Center
+2. Added public key to TX1
+3. Transferred backup via SCP (9.6MB @ 33.6MB/s)
+4. Verified transfer with MD5 checksum
+
+### Phase 4: TX1 Installation
+1. Created gitea system user and group
+2. Created directory structure
+3. Downloaded Gitea 1.21.5 binary
+4. Restored backup data
+5. Set correct permissions
+
+### Phase 5: Configuration
+1. Updated ROOT_URL in app.ini
+2. Created systemd service
+3. Enabled and started service
+4. Verified Gitea functionality on localhost
+
+### Phase 6: HTTPS Setup
+1. Installed Nginx as reverse proxy
+2. Configured proxy to Gitea (port 3000)
+3. Obtained Let's Encrypt SSL certificate
+4. Configured automatic HTTP→HTTPS redirect
+5. Updated Gitea ROOT_URL to HTTPS
+
+### Phase 7: DNS Update
+1. Updated Cloudflare A record
+   - Changed git.firefrostgaming.com from 63.143.34.217 to 38.68.14.26
+   - Kept DNS-only mode (gray cloud)
+2. Verified DNS propagation
+
+### Phase 8: Verification
+1. Generated post-migration file manifest
+2. Compared checksums (all 140 files matched perfectly)
+3. Tested web access via HTTPS
+4. Verified repository content on both branches
+5. Confirmed login functionality
+
+### Phase 9: Decommission
+1. Stopped Gitea on Command Center
+2. Disabled auto-start
+3. Preserved backup and data for safety
+
+---
+
+## Data Integrity Verification
+
+**Method:** MD5 checksum comparison
+
+**Pre-Migration Manifest:**
+- Location: `/root/gitea-migration-manifest.txt`
+- Files: 140
+- Generated: Feb 8, 22:02 CST
+
+**Post-Migration Manifest:**
+- Location: `/root/gitea-post-migration-manifest.txt`
+- Files: 140
+- Generated: Feb 8, 22:17 CST
+
+**Comparison Result:** ✅ **100% Match**
+- All 140 files transferred with identical MD5 checksums
+- Zero data corruption
+- Complete repository history preserved
+
+---
+
+## Technical Configuration
+
+### Nginx Reverse Proxy
+```nginx
+server {
+    server_name git.firefrostgaming.com;
+    
+    location / {
+        proxy_pass http://127.0.0.1:3000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded_Proto $scheme;
+    }
+    
+    listen 443 ssl;
+    ssl_certificate /etc/letsencrypt/live/git.firefrostgaming.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/git.firefrostgaming.com/privkey.pem;
+}
+```
+
+### SSL Certificate
+- **Provider:** Let's Encrypt
+- **Issued:** February 8, 2026
+- **Expires:** May 10, 2026 (90 days)
+- **Auto-Renewal:** Configured via Certbot
+
+### Gitea Configuration Changes
+```ini
+# Changed in /etc/gitea/app.ini
+ROOT_URL = https://git.firefrostgaming.com/
+```
+
+### Systemd Service
+```ini
+[Unit]
+Description=Gitea (Git with a cup of tea)
+After=network.target
+
+[Service]
+Type=simple
+User=gitea
+Group=gitea
+WorkingDirectory=/var/lib/gitea/
+ExecStart=/usr/local/bin/gitea web -c /etc/gitea/app.ini
+Restart=always
+Environment=USER=gitea HOME=/home/gitea GITEA_WORK_DIR=/var/lib/gitea
+
+[Install]
+WantedBy=multi-user.target
+```
+
+---
+
+## Firewall Configuration
+
+**UFW Rules (already present on TX1):**
+- Port 80/tcp: ALLOW (HTTP)
+- Port 443/tcp: ALLOW (HTTPS)
+- Port 22/tcp: ALLOW (SSH via OpenSSH)
+
+---
+
+## Repository Branch Structure
+
+### master (Source of Truth)
+- **Default:** Yes
+- **Content:** Full operations manual
+- **Files:** 15+ markdown documents, diagrams folder
+- **Purpose:** Active development and documentation
+
+### main
+- **Default:** No
+- **Content:** Initial setup files (GITEA_README.md, docs/USER_GUIDE.md)
+- **Purpose:** Historical reference
+
+**Note:** Future cleanup recommended to consolidate branches.

+
+## Post-Migration Status
+
+### Services Running on TX1
+- ✅ Gitea 1.21.5 (port 3000)
+- ✅ Nginx reverse proxy (ports 80, 443)
+- ✅ Certbot auto-renewal timer
+
+### Access
+- **URL:** https://git.firefrostgaming.com
+- **SSL:** Valid (Let's Encrypt)
+- **Status:** Operational
+
+### Services Stopped on Command Center
+- ⏸ Gitea (stopped and disabled)
+- 💾 Backup preserved at `/root/gitea-backup-20260208-2203.tar.gz`
+
+---
+
+## Lessons Learned
+
+### What Went Well
+1. **Small repository size** (13MB) made migration quick and easy
+2. **MD5 checksum verification** provided confidence in data integrity
+3. **SQLite database** (single file) simplified backup/restore
+4. **Server-to-server SSH** enabled fast, secure transfer
+5. **DNS propagation** was nearly instant (gray cloud mode)
+
+### Challenges
+1. **Initial 502 error** - Resolved by restarting Nginx
+2. **Two-branch confusion** - Identified master as source of truth
+3. **Firewall already configured** - Saved time but worth documenting
+
+### Recommendations for Future Migrations
+1. Always create file manifests for verification
+2. Test HTTPS locally before DNS update
+3. Keep backups on source server for 30 days
+4. Document branch structure before migration
+5. Consider branch cleanup as follow-up task
+
+---
+
+## Backup Strategy
+
+### Command Center
+- **Location:** `/root/gitea-backup-20260208-2203.tar.gz`
+- **Size:** 9.6MB
+- **Retention:** 30 days minimum
+- **Purpose:** Rollback capability
+
+### TX1
+- **Location:** `/root/gitea-backup-20260208-2203.tar.gz`
+- **Size:** 9.6MB
+- **Purpose:** Pre-installation reference
+
+### Manifest Files
+- Command Center: `/root/gitea-migration-manifest.txt`
+- TX1: `/root/gitea-post-migration-manifest.txt`
+
+---
+
+## Future Considerations
+
+### Maintenance Tasks
+1. **SSL Renewal:** Automatic via Certbot (verify monthly)
+2. **Gitea Updates:** Check for updates quarterly
+3. **Backup Rotation:** Implement automated backups on TX1
+4. **Branch Cleanup:** Consolidate master/main branches
+
+### Monitoring
+- **Uptime Kuma:** Add git.firefrostgaming.com to monitoring (Phase 0.5)
+- **SSL Expiry:** Monitor certificate expiration
+- **Service Status:** Include in Netdata dashboard
