  - "/srv/mergerfs/DataPool/nextcloud/config:/var/www/html/config"

immich:
  - Large PostgreSQL database with vector search
  - ML model cache requires GPU access

Phase 3: Development & Productivity

Complexity: Medium to High

Service Stack	Components	Dependencies
AppFlowy Cloud	9 containers	postgres + redis + minio + nginx
Gitea	Single container	Git repository data
Paperless-NGX	3 containers	Database + Redis + Document processing

Phase 4: Monitoring & Management

Complexity: Low (final cleanup)

• Portainer agents (6 instances)
• Watchtower auto-updaters
• Uptime Kuma monitoring
• Log aggregation (Dozzle)

Critical Data Migration Map

High-Priority Data Requiring Backup

Path	Service	Estimated Size	Backup Strategy
/srv/mergerfs/DataPool/nextcloud/	Nextcloud	Large	Database dump + rsync
/srv/mergerfs/DataPool/Movies/	Jellyfin	Very Large	Direct transfer/mounting
/srv/mergerfs/DataPool/tv_shows/	Jellyfin	Very Large	Direct transfer/mounting
Home Assistant config	Home Assistant	Small	Critical config backup
PostgreSQL databases	Multiple	Medium	pg_dump before migration

Docker Volume Inventory

Named Volumes Requiring Migration:

• jellyfin-config - Jellyfin configuration
• jellyfin-cache - Transcoding cache (can rebuild)
• immich_model-cache - ML models (large, can redownload)
• paperless_pgdata - Document database
• vikunja-db - Task management database

Service Dependencies & Orchestration

Critical Dependency Chains

Container Recreation Templates

# Example for high-complexity services
jellyfin:
  image: "jellyfin/jellyfin:latest"
  ports:
    - "8096:8096"
  volumes:
    - "jellyfin-config:/config"
    - "jellyfin-cache:/cache"
  bind_mounts:
    - "{{media_path}}/Movies:/media/movies"
    - "{{media_path}}/tv_shows:/media/tv_shows"
  environment:
    - "NVIDIA_VISIBLE_DEVICES=all"
    - "NVIDIA_DRIVER_CAPABILITIES=compute,video,utility"
  restart: "unless-stopped"
  health_check:
    test: ["CMD-SHELL", "curl --noproxy 'localhost' -Lk -fsS http://localhost:8096/health"]
    interval: "30s"

Migration Validation Checklist

Per-Service Validation

• Container health checks passing
• Port accessibility verified
• Volume mounts correct
• Network connectivity confirmed
• Service-specific functionality tested

System-Level Validation

• DNS resolution working (AdGuard/Unbound)
• Media streaming functional (Jellyfin)
• File sync operational (Nextcloud)
• Home automation responsive (Home Assistant)
• Photo AI processing working (Immich)
• Document management operational (Paperless-NGX)

Resource Requirements

Target Infrastructure Minimum Specs

• CPU: 8+ cores (for containerized workload)
• Memory: 32GB+ (databases + media processing)
• Storage:
  • NVMe SSD for databases and hot data
  • Bulk storage for media files (20TB+)
  • Network-attached storage capability
• Network: Gigabit ethernet minimum, 10Gbit preferred
• GPU: Optional but recommended for Jellyfin transcoding

Container Resource Allocation

resource_tiers:
  high_resource:
    - immich_machine_learning (GPU acceleration)
    - jellyfin (transcoding)
    - nextcloud (file processing)
    - home_assistant (many integrations)
  
  medium_resource:
    - database_containers (postgres, mariadb, redis)
    - appflowy_stack (development environment)
  
  low_resource:
    - monitoring_containers (portainer, watchtower)
    - dns_services (adguard, unbound)

Migration Risk Assessment

High-Risk Services

1. Home Assistant - Critical for home automation, device dependencies
2. Nextcloud - Large user data, database dependencies
3. DNS Services - Network-wide impact if misconfigured

Medium-Risk Services

1. Jellyfin - Large media libraries, transcoding setup
2. Immich - Complex ML pipeline, large photo libraries
3. AppFlowy Stack - Multiple interdependent containers

Low-Risk Services

1. Monitoring tools - Can be rebuilt easily
2. Development containers - Non-production workloads

Rollback Strategy

• Keep original services running during migration
• Validate each service before decommissioning source
• Database backups before any database migration
• Configuration snapshots for quick recovery
