🗺️ Migration Paths & Alternatives

Conservative Path (Recommended)

Phase 1 ✅ → Wait 6 months → Evaluate Phase 2 → Implement gradually

Aggressive Path (For Learning)

Phase 1 ✅ → Phase 2 (2 weeks) → Phase 3 (1 month) → Evaluate

Hybrid Approaches

Docker Swarm Alternative (Simpler than Kubernetes)

# docker-swarm/stack.yml
version: '3.8'
services:
  web:
    image: nginx
    deploy:
      replicas: 3
      update_config:
        parallelism: 1
        delay: 10s
      restart_policy:
        condition: on-failure

Nomad Alternative (HashiCorp ecosystem)

# nomad/web.nomad
job "web" {
  datacenters = ["homelab"]
  
  group "web" {
    count = 3
    
    task "nginx" {
      driver = "docker"
      config {
        image = "nginx:latest"
        ports = ["http"]
      }
    }
  }

🔄 Rollback Strategy

Each phase is designed to be reversible:

• Phase 2: Keep existing Portainer setup, add Terraform gradually
• Phase 3: Run orchestration alongside existing containers
• Phase 4: Monitoring and security are additive
• Phase 5: AI components are optional enhancements

Golden Rule: Never remove working systems until replacements are proven.
