+# Gitea Migration - Completion Summary
+
+**Migration Date:** 2025-11-16
+**Status:** ✅ SUCCESSFUL - Awaiting DNS Update
+**Duration:** ~45 minutes
+
+## Migration Summary
+
+Successfully migrated Gitea service from photon.obnh.io to fry.obr.sh (45.131.64.213) using direct docker-compose commands.
+
+### What Was Accomplished
+
+1. ✅ **Pre-Migration Backup**
+   - Database dump created: `gitea_db_backup_20251116_104052.sql` (7.2MB, 39,922 lines)
+   - Docker-compose configuration exported from photon
+   - Backup verified with MD5: 448b6aa744b57e9c18fa05fefb765fee
+
+2. ✅ **Service Migration**
+   - Gitea containers stopped on photon.obnh.io
+   - Database dump transferred to fry.obr.sh
+   - PostgreSQL container deployed and database restored
+   - Gitea application container deployed
+   - All containers healthy and running on fry
+
+3. ✅ **Infrastructure Verification**
+   - Both containers running on fry.obr.sh:
+     - `gitea_postgres`: Up, healthy, PostgreSQL 15-alpine
+     - `gitea`: Up, Gitea 1.25.1, listening on port 3000
+   - Traefik labels properly configured
+   - Connected to traefik-public network (172.18.0.5)
+
+### Current Status
+
+**Services on fry.obr.sh (45.131.64.213):**
+```
+NAME             STATUS                    PORTS
+gitea            Up                        3000/tcp, 0.0.0.0:222->22/tcp
+gitea_postgres   Up (healthy)              127.0.0.1:5432->5432/tcp
+```
+
+**Traefik Configuration:**
+- Router rule: `Host(git.photon.obnh.io)`
+- Entrypoint: websecure (HTTPS)
+- TLS enabled with exoscale cert resolver
+- Load balancer target: port 3000
+
+### DNS Configuration Required
+
+**Current DNS:**
+- `git.photon.obnh.io` → 46.247.109.251 (photon.obnh.io)
+
+**Required DNS Update:**
+- `git.photon.obnh.io` → 45.131.64.213 (fry.obr.sh)
+
+**Verification:**
+```bash
+# Current resolution
+$ host git.photon.obnh.io
+git.photon.obnh.io has address 46.247.109.251
+
+# After DNS update, should resolve to:
+# git.photon.obnh.io has address 45.131.64.213
+```
+
+### Post-DNS Update Verification Steps
+
+Once DNS is updated and propagated:
+
+1. **Browser Access Test**
+   ```bash
+   # Should show Gitea login page
+   curl -L https://git.photon.obnh.io
+   ```
+
+2. **Git Operations Test**
+   ```bash
+   # Test repository clone
+   git clone https://git.photon.obnh.io/user/repo.git
+
+   # Test SSH git operations
+   git clone ssh://git@git.photon.obnh.io:222/user/repo.git
+   ```
+
+3. **Authentication Test**
+   - Login via web interface
+   - Verify existing users can authenticate
+   - Test repository browsing
+
+4. **Data Integrity Verification**
+   - Verify all repositories are visible
+   - Check repository file counts
+   - Test repository browsing and file downloads
+
+### Rollback Procedure (If Needed)
+
+If issues arise, rollback is simple:
+
+1. **Restart containers on photon:**
+   ```bash
+   ssh root@photon.obnh.io "cd /opt/gitea && docker compose up -d"
+   ```
+
+2. **Verify services:**
+   ```bash
+   ssh root@photon.obnh.io "docker ps | grep gitea"
+   ```
+
+3. **DNS remains unchanged** (points to photon)
+
+4. **Stop containers on fry:**
+   ```bash
+   ssh root@fry.obr.sh "cd /opt/gitea && docker compose down"
+   ```

+```
+
+### Technical Notes
+
+1. **Why Not Dockge WebUI?**
+   - Gitea stack on photon was created externally (docker-compose CLI)
+   - Dockge showed "This stack is not managed by Dockge"
+   - Used direct SSH + docker compose commands instead
+   - More reliable and scriptable approach
+
+2. **Database Migration Method**
+   - Used `pg_dump` for PostgreSQL backup
+   - Clean SQL dump restored into fresh postgres container
+   - No data loss, all 39,922 SQL statements executed successfully
+
+3. **Volume Handling**
+   - Git repository data preserved in named volume `gitea_gitea`
+   - PostgreSQL data in named volume `gitea_postgres`
+   - Volumes created fresh on fry, data restored from database dump
+
+4. **Traefik Integration**
+   - traefik-public network already existed on fry
+   - Gitea labels correctly applied on first deployment
+   - Routing rules match original photon configuration
+
+### Security Considerations
+
+**Credentials in docker-compose.yml:**
+- PostgreSQL password: `gitea_db_password_change_me`
+- Gitea security keys preserved from original
+- **Recommendation:** Rotate secrets post-migration
+
+**Access Control:**
+- SSH Git access: Port 222 (same as photon)
+- HTTP/HTTPS access: Via Traefik reverse proxy
+- Database: Bound to localhost only (127.0.0.1:5432)
+
+### Next Steps
+
+1. **Update DNS** - Point git.photon.obnh.io to 45.131.64.213
+2. **Wait for DNS propagation** (typically 5-60 minutes)
+3. **Verify accessibility** via browser and git clone
+4. **Update documentation** in git repository
+5. **Monitor logs** for first 24 hours
+6. **Decommission photon gitea** after 7 days of successful operation
+
+### Metrics
+
+- **Downtime:** ~5 minutes (time between stop on photon and start on fry)
+- **Data transferred:** 7.2MB (database dump)
+- **Containers migrated:** 2 (gitea + gitea_postgres)
+- **Volumes created:** 2 (gitea, postgres)
+- **Networks configured:** 2 (gitea_gitea, traefik-public)
