Post-Merger IT Integration (M&A)
M&A programs need a clear technical thread from Day-1 identity and collaboration through long-term platform consolidation. We combine enterprise architecture with pragmatic sequencing—so integration does not stall on unresolved directory conflicts or duplicate cloud estates.
The fastest integrations align executives on a target operating model early; the slowest ones debate tenant strategy in month eighteen.
Tenant, identity, and collaboration convergence
We evaluate single vs multi-tenant paths for Entra ID and Microsoft 365, mail coexistence, Teams, SharePoint, and guest access. Day-1 experiences for users are designed explicitly—branding, support channels, and emergency access included.
Azure subscriptions & landing zone harmonization
Overlapping subscriptions, duplicate networking, and conflicting policies are mapped to a target landing zone model. Cost allocation and chargeback are adjusted so the merged entity does not carry invisible duplicate spend for years.
Application rationalization & data migration
Duplicate apps, overlapping data stores, and integration spaghetti are categorized: retire, replace, integrate, or migrate. Data migration waves respect compliance, residency, and business cutover windows.
Program governance & stakeholder alignment
We produce steering-ready views: dependency graphs, wave plans, risk registers, and decision logs. Technical work stays tied to synergy targets and integration management office milestones.
Outcomes you can expect
- A single, defensible target picture for identity, collaboration, and cloud
- Reduced duplicate licensing and shadow IT sprawl post-close
- Clear wave plan with owners, dates, and rollback criteria
- Fewer user-facing disruptions through explicit coexistence design
- Executive transparency: risks and costs visible before they become crises
