What is an M&A Microsoft 365 Tenant Migration Assessment?
A 4-week fixed-fee engagement that assesses M&A target/acquirer Microsoft 365 tenants for migration readiness. Output: Day-1 readiness plan + 90-day cutover roadmap + identity merge architecture + SharePoint consolidation plan + license rationalization model. Required for any M&A deal closing with M365 integration in scope.
What is Day-1 readiness in an M&A M365 context?
Day-1 readiness means: target employees can authenticate via acquirer Entra ID on Day 1 of close, target email is reachable (transport rule or migrated), critical shared content is accessible, and Microsoft Teams cross-tenant access works. Full tenant consolidation typically takes 6-18 months post-close; Day-1 is the minimum-viable cutover.
When should we run this assessment?
Optimal timing: 30-60 days before deal close. Required: BEFORE you announce close date publicly. Worst case: post-close (assessment still valuable but you're working against the clock).
How much does the M&A Tenant Migration Assessment cost?
Fixed-fee $40,000-$75,000 based on deal complexity: simple merge (single target, single geo, similar industry) $40K, complex merge (multi-target, multi-geo, regulated industry) $55K, carve-out (separating from parent) $75K. ROI: typically prevents $200K-$2M in post-close migration cost overruns.
What deliverables come from the assessment?
5 documents: (1) Target + Acquirer tenant inventory + comparison report, (2) Day-1 readiness plan + cutover runbook, (3) 90-day post-close migration roadmap, (4) Identity merge architecture (Entra ID + on-prem AD + B2B + SAML), (5) License rationalization model with quantified savings.
Does EPC Group also do the migration execution?
Yes. EPC Group Microsoft 365 M&A Migration: $200K-$3M depending on tenant size + deal complexity. 12-36 weeks typical. Day-1 cutover + 90-day full migration + 12-month optimization. Carve-out migrations (separating from parent tenant) are a specialized variant.
What about private equity portfolio standardization?
EPC Group has a dedicated Private Equity Portfolio Microsoft Practice. We standardize M365 + SharePoint + Power Platform + Dynamics 365 across PE portfolio companies, accelerating value creation through unified governance + shared services. See /services/private-equity-microsoft-practice.
Does this include carve-out scenarios (separating from parent)?
Yes. Carve-out migrations are the inverse pattern of M&A merges: separating a business unit's M365 tenant from a parent company tenant. EPC Group has executed 12+ Fortune 500 carve-outs. See /services/carve-out-microsoft-365-migration.
