M&A & IT Integration
IT Integration for Mergers & Acquisitions
IT determines the success or failure of a transaction. We manage the entire process — from due diligence to the last migrated mailbox.
Challenges
What can go wrong in M&A projects
Fact-based insights from real integration projects.
Incomplete IT Due Diligence
License counts don't match, undocumented systems surface, the IT manager has already resigned. Without a thorough assessment, you're starting blind.
Missing Coexistence Strategy
Employees from both companies need to collaborate from day one. Without planned coexistence (GAL sync, calendar sharing, Teams federation), productivity losses occur immediately.
Underestimated Dependencies
Exchange migrations depend on DNS, Conditional Access, certificates, third-party apps. A single overlooked link can jeopardize the entire timeline.
No Dedicated Project Management
70–90 % of M&A deals fail to meet their goals. When IT integration runs as a side task, it becomes a risk factor instead of a success factor.
Our Approach
Structured from Day 1
Five phases from analysis to completion — each with clear deliverables and milestones.
IT Due Diligence & Assessment
Systematic inventory of both IT landscapes: tenants, licenses, identities, security policies, dependencies. Result: Clear status report and risk analysis.
Migration Strategy & TSA Planning
Definition of migration paths, coexistence requirements, and Transitional Service Agreements. Which systems first? Which dependencies? Which deadlines?
Establish Coexistence
GAL sync, calendar sharing, Teams federation, mail routing — so both organizations can work together productively right away. Supported by Quest coexistence tools.
Execute Tenant Migration
Exchange Online, OneDrive, SharePoint, Teams, Power BI, Active Directory. Tool-supported with Quest On Demand Migration and with minimal downtime.
Validation & Completion
Post-migration testing, user communication, documentation, handover. The project is only complete once everything has been validated.
Tools & Partnerships
Proven tools, certified methodology
Is an M&A transaction on the horizon?
Talk to us early — ideally before closing. The sooner we're involved, the smoother the IT integration will be.
