1. What problem does this solve?
Manual, ad-hoc migrations lead to extended downtime, data loss, unpredictable costs, and high failure rates when attempting to scale beyond a few dozen applications.
Why is the traditional approach broken?
Traditional IT teams attempt "lift and shift" using disparate scripts and manual server builds. Dependency mapping is usually done via spreadsheets, leading to broken application tiers when a database is migrated without its web frontend.
2. How does MacroCloud solve it?
MacroCloud provides a fully automated Migration Factory pipeline. We deploy discovery agents to automatically map dependencies across the datacenter, intelligently group workloads into Migration Waves, and orchestrate block-level replication using native tools (AWS MGN / Azure Migrate) to ensure zero data loss.
3. Implementation Phases
This architecture is deployed via infrastructure-as-code following this exact sequence:
4. Operational Considerations & Risks
Operations
- Monitoring replication lag (RPO) metrics
- Executing non-disruptive test failovers
- Updating DNS records post-cutover
Risks
- Bandwidth saturation on Direct Connect during initial sync
- Undiscovered hardcoded IP addresses failing post-migration
- Legacy OS versions unsupported by cloud hypervisors
Business Outcomes
- Predictable, zero-downtime cutover windows
- 100% dependency mapping accuracy
- Parallel migration of up to 500 VMs per wave
Core Components
- Agentless Discovery Appliance
- Replication Servers (AWS MGN / Azure Migrate)
- Automated Cutover Runbooks
