M&A in the field.
What it looks like when it works.
Real acquisition scenarios. Real discovery data. Real migrations delivered. Each case study documents the complexity that was hiding beneath the surface — and how teams used ACQI to eliminate it before it became a crisis.
Four Azure tenants. One migration window. Zero surprises.
Three regional acquisitions in 14 months. Each subsidiary ran its own Azure tenant, Active Directory forest, and M365 environment. The board set an 18-week integration deadline — with no structured IT inventory for any of the three acquired entities.
Key outcomes
47,312 identities spread across four separate forests. 340 applications fingerprinted, 12 of them undocumented legacy systems. GDPR violations in EU tenants, FCA requirements in the UK entity. 18 weeks to consolidate everything before duplicate infrastructure costs hit £400K per week.
- 4 separate IT teams, no unified asset register
- Cross-tenant dependencies undiscovered
- GDPR + FCA + MAS compliance obligations
ACQI deployed on Day 1 across all four tenants simultaneously. 124 discovery modules executed in parallel. Discovery data fed directly into migration planning — no manual handoff. Wave-based migration with Go/No-Go gates at each phase boundary.
- Deployed Day 1 across all 4 tenants
- 124 modules in parallel across Azure, AD, M365
- Wave-based migration with Go/No-Go gates
Why discovery comes before migration
Most M&A IT overruns follow the same pattern: a team starts migrating without complete visibility into what they're moving. An undocumented application surfaces mid-migration. A conditional access policy conflict breaks authentication for a business-critical system. An AD trust with an unknown service account dependency causes a production outage at 3am.
The multi-tenant consolidation in this case study avoided all of that. ACQI ran 124 discovery modules across all four environments in the first three weeks. Every identity, every application, every policy, every dependency was catalogued and cross-referenced before a single migration window was booked.
The result: six migration waves executed with zero P1 incidents. 47,000+ identities migrated with 99.7% cutover success. £2.1M in IT synergies identified through governance tracking running in parallel with integration milestones.
Discovery is not optional in M&A integration. It is the work. Everything that follows is just executing against a known state.
Running an acquisition right now?
The fastest path to a successful consolidation is knowing exactly what you're consolidating. ACQI has the modules. Start scanning on Day 1.
