Day 1 critical
Keep the business operating.
Identity, access, connectivity, service ownership, support routes and operational escalation should work immediately when the transaction closes.
M&A Advisory · Post-Merger Integration
Turn the transaction into one operating technology environment without forcing every decision to happen on the same day.
Post-merger integration needs a sequencing model. Some technology choices must be ready for Day 1, some can stabilize over the first 100 days and some belong in a deliberate longer-range target-state program.

Integration Priorities
Not everything should integrate at the same speed.
Integration should reflect business criticality, risk, operating dependency, contract timing and the level of change the organization can absorb without losing continuity.
First 100 days
Stabilize and reduce complexity.
Address overlapping tools, duplicated vendors, documentation gaps, operating handoff issues and visible architectural friction.
Longer-range
Move toward the target state.
Deliberately restructure platforms, architecture, data models and operating patterns once the merged business has enough stability to absorb deeper change.
Connected Workstreams
Coordinate technology integration as connected workstreams rather than isolated projects.
Technology integration cuts across systems, infrastructure, data, security, vendors and operating support. The work becomes more manageable when each stream is visible and tied to the same integration logic.
Applications
Rationalize systems and platform overlap.
Decide what should be retained, merged, sunset or temporarily tolerated while business processes continue operating.
Infrastructure & cloud
Protect resilience while environments change.
Support networking, hosting, monitoring, backup, continuity and environment-level control as ownership structures shift.
Data & integration
Clarify what data must move, connect or remain separate.
Map dependencies between applications, reporting, integrations and critical datasets before change creates hidden failure points.
Integration Sequence
Use milestones that protect operations while moving toward the target state.
Milestones create pacing. They help leadership see what must happen before close, what matters immediately after close and when larger changes should start.
Before close
Define the Day 1 minimum.
Document the systems, access patterns, support ownership, vendor dependencies and operational routes required for a stable handoff.
Day 1–30
Stabilize the combined operating environment.
Control immediate disruption, close visibility gaps, monitor incidents and confirm the technology model actually works in the live business.
Day 30–100
Sequence consolidation and remediation.
Start the changes that reduce duplicated cost, operational friction and fragmented ownership, but only when the merged business can absorb the work without losing control.
100+ days
Advance the longer-range target state.
Move into architecture rationalization, estate simplification, platform modernization and deeper transformation once the foundation is stronger.
Integration Governance
Make decisions fast enough for the business while preserving architecture, control and accountability.
Governance should not become bureaucracy. It should keep decision rights visible, define escalation paths and ensure one merged business does not inherit hidden technology ambiguity.
Decision structure
Integration works better when ownership is unmistakable.
Clarify who decides, who executes, who approves exceptions and how the merged business resolves cross-stream conflicts.
Decision rights
Name business and technology owners for platform, data, security, operations and vendor decisions.
Escalation path
Define how issues move when timing, risk or cost creates disagreement between workstreams.
Change control
Prevent uncontrolled fixes, duplicate work and local changes that break the integration logic.
Operating cadence
Use a simple rhythm for reporting, dependency review, decision follow-up and milestone management.
M&A Advisory Paths
Move across the five technology workstreams connected to the transaction.
