Major infrastructure migration and Vaultwarden PostgreSQL troubleshooting

COMPREHENSIVE CHANGES:

INFRASTRUCTURE MIGRATION:
- Migrated services to Docker Swarm on OMV800 (192.168.50.229)
- Deployed PostgreSQL database for Vaultwarden migration
- Updated all stack configurations for Docker Swarm compatibility
- Added comprehensive monitoring stack (Prometheus, Grafana, Blackbox)
- Implemented proper secret management for all services

VAULTWARDEN POSTGRESQL MIGRATION:
- Attempted migration from SQLite to PostgreSQL for NFS compatibility
- Created PostgreSQL stack with proper user/password configuration
- Built custom Vaultwarden image with PostgreSQL support
- Troubleshot persistent SQLite fallback issue despite PostgreSQL config
- Identified known issue where Vaultwarden silently falls back to SQLite
- Added ENABLE_DB_WAL=false to prevent filesystem compatibility issues
- Current status: Old Vaultwarden on lenovo410 still working, new one has config issues

PAPERLESS SERVICES:
- Successfully deployed Paperless-NGX and Paperless-AI on OMV800
- Both services running on ports 8000 and 3000 respectively
- Caddy configuration updated for external access
- Services accessible via paperless.pressmess.duckdns.org and paperless-ai.pressmess.duckdns.org

CADDY CONFIGURATION:
- Updated Caddyfile on Surface (192.168.50.254) for new service locations
- Fixed Vaultwarden reverse proxy to point to new Docker Swarm service
- Removed old notification hub reference that was causing conflicts
- All services properly configured for external access via DuckDNS

BACKUP AND DISCOVERY:
- Created comprehensive backup system for all hosts
- Generated detailed discovery reports for infrastructure analysis
- Implemented automated backup validation scripts
- Created migration progress tracking and verification reports

MONITORING STACK:
- Deployed Prometheus, Grafana, and Blackbox monitoring
- Created infrastructure and system overview dashboards
- Added proper service discovery and alerting configuration
- Implemented performance monitoring for all critical services

DOCUMENTATION:
- Reorganized documentation into logical structure
- Created comprehensive migration playbook and troubleshooting guides
- Added hardware specifications and optimization recommendations
- Documented all configuration changes and service dependencies

CURRENT STATUS:
- Paperless services: ✅ Working and accessible externally
- Vaultwarden: ❌ PostgreSQL configuration issues, old instance still working
- Monitoring: ✅ Deployed and operational
- Caddy: ✅ Updated and working for external access
- PostgreSQL: ✅ Database running, connection issues with Vaultwarden

NEXT STEPS:
- Continue troubleshooting Vaultwarden PostgreSQL configuration
- Consider alternative approaches for Vaultwarden migration
- Validate all external service access
- Complete final migration validation

TECHNICAL NOTES:
- Used Docker Swarm for orchestration on OMV800
- Implemented proper secret management for sensitive data
- Added comprehensive logging and monitoring
- Created automated backup and validation scripts

+# MIGRATION PROGRESS SUMMARY
+**Generated:** 2025-08-29  
+**Status:** Core Infrastructure Complete - Ready for Service Migration
+
+---
+
+## 🎯 **COMPLETED WHILE BACKUPS RUN**
+
+### **✅ Core Database Infrastructure**
+- **PostgreSQL**: ✅ Running (1/1 replicas)
+- **MariaDB**: ✅ Running (1/1 replicas)  
+- **Redis**: ✅ Running (1/1 replicas)
+
+### **✅ Docker Swarm Foundation**
+- **All 6 nodes joined**: OMV800, audrey, fedora, lenovo410, lenovo420, surface
+- **Overlay networks created**: database-network, caddy-public, monitoring-network
+- **Secrets management**: All required secrets configured
+- **Node labeling**: OMV800 configured as database node
+
+### **✅ Migration Preparation**
+- **Caddyfile backup**: Created with timestamp
+- **Migration templates**: Ready for parallel deployment
+- **Rollback scripts**: Emergency rollback procedures ready
+- **Migration checklist**: Comprehensive validation steps
+
+---
+
+## 🚀 **READY FOR NEXT PHASE**
+
+### **Phase 1: Application Service Deployment**
+Now that core infrastructure is complete, we can deploy application services:
+
+1. **Low-Risk Services First**:
+   - Mosquitto (MQTT broker)
+   - Monitoring services (Netdata, Uptime Kuma)
+
+2. **Medium-Risk Services**:
+   - Nextcloud
+   - AppFlowy
+   - Jellyfin
+
+3. **High-Risk Services** (after validation):
+   - Home Assistant
+   - Paperless
+   - Vaultwarden
+
+### **Phase 2: Parallel Deployment Strategy**
+- Deploy services to swarm alongside existing services
+- Test new endpoints while keeping old ones
+- Gradual traffic migration
+- Zero-downtime cutover
