M&A IT Integration
When companies merge, we merge their IT.
IT integration is the most overlooked part of any acquisition. Two tenants, two vendor stacks, two security policies, two ways of doing everything. We fix that, on schedule and without disrupting operations.
- Pre-close
- IT due diligence & risk assessment
- 30-90 days
- Typical integration timeline
- Zero
- Disruption to daily operations
- 2 tenants
- Merged into one environment
The problem
IT integration is where deals get expensive.
We've seen this before. The technology side of an acquisition is rarely planned for, and the costs show up after close, when two companies discover they can't actually work together. Here's how it goes wrong.
- 01
IT is always an afterthought
The deal team focuses on financials and legal. IT gets ignored, until the deal closes and suddenly nothing works the way it should.
- 02
Two Microsoft 365 tenants
Two separate tenants that now need to become one. Email, files, Teams, and identity all have to be merged without losing data or breaking access.
- 03
Different domains, tools, and logins
Employees show up with different email domains, different applications, and different logins. Collaboration grinds to a halt before integration even starts.
- 04
No one knows who has access to what
Permissions are a mystery across both environments. Orphaned accounts, shared credentials, and unclear ownership become real liabilities.
- 05
Security gaps multiply
When two environments merge without a plan, security policies conflict and gaps open up. Acquisitions are exactly when attackers come looking.
- 06
The acquiring IT team is stretched thin
Internal IT is already running the existing business. Layering a full integration on top of their day job is how timelines slip and mistakes happen.
What we handle
The technical work of bringing two companies together.
Every integration is different, but the building blocks are the same. Here's the work we own so your team can stay focused on the business.
Microsoft 365 tenant migrations
Migrate or consolidate two tenants into one: mail, files, Teams, and SharePoint.
Entra ID / Active Directory consolidation
Merge identity directories so every employee has one account and one set of access.
Email domain unification
Route mail across domains during transition, then unify under a single identity.
Endpoint deployment & standardization
Deploy RMM, EDR, and backup across acquired devices to a common, managed standard.
Network integration across offices
Connect locations, establish site-to-site VPN, and unify the network footprint.
Vendor audit & rationalization
Identify overlapping tools and contracts, then eliminate the redundant ones.
License consolidation & optimization
Right-size Microsoft and third-party licensing to cut waste after the merge.
Security posture alignment
Reconcile conflicting policies into one hardened standard across both environments.

Our process
A proven M&A IT integration methodology.
We've run this playbook through every stage of the deal lifecycle. Four phases, from pre-close diligence to a fully integrated, managed environment.
- Step 1
Pre-Close Due Diligence
Before the deal closes
- IT environment assessment of the target company
- Identify integration complexity, risks, and timeline
- Inventory of endpoints, networks, applications, and vendors
- Report delivered to deal team with recommendations
- Step 2
Day 1 Readiness
The day the deal closes
- Email routing and domain strategy
- Shared access to critical systems
- Temporary coexistence policies
- Communication to both employee bases
- Step 3
Integration Execution
30-90 days post-close
- Microsoft 365 tenant migration or consolidation
- Identity consolidation (AD / Entra ID merge)
- Endpoint standardization: RMM, EDR, and backup across acquired devices
- Network integration: connect offices, establish VPN
- Vendor rationalization: eliminate redundant tools and contracts
- Step 4
Steady State
90+ days
- Transition to ongoing managed services
- Unified monitoring and support
- Quarterly business reviews
- Documentation of the integrated environment
FAQ
Common questions.
Have a different question? Reach out directly.
How early should we engage you?
Ideally before the deal closes. Pre-close IT due diligence helps you understand integration costs and risks while you still have leverage. But we can engage at any stage, including after close, when the integration is already underway.
How long does a typical integration take?
30-90 days for most mid-market deals, depending on complexity. Simple tenant migrations can be faster; multi-location, multi-domain environments take longer. We give you a realistic timeline up front during the assessment.
Do you handle IT for both companies during integration?
Yes. We manage the transition period where both environments coexist, keeping everyone productive, then consolidate everything into a single managed environment.
Can you become the ongoing MSP after integration?
Absolutely, most of our M&A clients transition to our managed services. The integration is how the relationship starts, and ongoing support is how it continues.
What if the target company has a different tech stack?
That's the norm. We've handled migrations from Google Workspace to Microsoft 365, on-prem Exchange to cloud, and everything in between. Different stacks are exactly what we plan for.
Have a deal closing? Let's talk before IT becomes the bottleneck.
Book a discovery call and we'll walk through your integration. We can typically begin a pre-close assessment within one week.
