M&A Due Diligence & Workload Migration Engine¶
M&A Playbook Enterprise Migration
1. Mergers & Acquisitions Strategic Framework¶
Healthcare systems scale rapidly through regional hospital acquisitions and joint venture partnerships. Integrating disparate legacy infrastructure into the Mosaic Azure Landing Zone within aggressive 90-day timeframes requires a standardized, repeatable engineering engine.
The Mosaic M&A Workload Migration Engine bridges the gap between pre-close technical due diligence, cyber risk quarantine, 5-R workload rationalization, and zero-downtime clinical EHR cutovers.

2. Core Playbook Components¶
- Due Diligence Technical Checklist
Comprehensive 8-pillar technical audit framework assessing Active Directory domain functional levels, virtualization hypervisors (VMware ESXi / Hyper-V), SAN storage throughput, public cloud assets, and regulatory compliance liabilities. - Wave Migration Sequencer & Rollback Triggers
Step-by-step cutover orchestration model outlining dependency grouping, wave scheduling, real-time database replication synchronization, pre-flight gate criteria, and automated rollback triggers.
