IT Carve Out Migration Services
Divestitures run on fixed M&A deal timelines. WME helps organizations separate IT infrastructure, migrate data, and achieve readiness right on Day 1 without disrupting business operations.
Separating IT Systems Without Separating the Business.
Are Your Systems Ready to Stand on Their Own after Separation?
When your business unit splits from the parent, your IT doesn’t split cleanly. Your users, data, and applications are still tied into shared systems, from ERP and Microsoft 365 to network access and core operational data.
If those dependencies are not identified and separated early, they turn into delays, disruptions, and operational risk right when your business needs stability most.

Are Your Systems Ready to Stand on Their Own after Separation?
When your business unit splits from the parent, your IT doesn’t split cleanly. Your users, data, and applications are still tied into shared systems, from ERP and Microsoft 365 to network access and core operational data.
If those dependencies are not identified and separated early, they turn into delays, disruptions, and operational risk right when your business needs stability most.
Operating model gaps
The separated entity needs its own ERP system, infrastructure, and support services. These can't be stood up at the last minute.
Change management
End-users need preparation. Without it, employees cannot access systems or complete basic business processes.
Timeline compression
Fixed legal close dates leave little runway. Poor due diligence early in the project is the most common cause of early failures.
Compliance Risks
Carve-outs move sensitive data across legal boundaries. Data protection obligations don't pause during transition. Any exposure creates regulatory exposure.
Data integrity
When master data lives in shared tables, splitting it without corruption requires transformation logic and quality assurance at every stage of the migration process.
Shared IT infrastructure
The parent company and carved-out entity often share the same systems and networks. Separating them without service interruption requires precise sequencing instead of a simple cutover.
An M&A deal closes on a fixed date. The IT carve-out has to close on the same one. That pressure, layered on top of shared system complexity, is where risk builds up.
Why Carve-Out Projects Are High Risk
Which Systems Need to Be Separated?
SAP S/4HANA & SAP ERP Separation
An SAP carve-out is one of the most complex parts of any separation. Company codes, business processes, and both master and transactional data must be cleanly separated across the SAP landscape, often requiring structured extraction and reconfiguration of tightly coupled systems. Both the source and target environments must be fully validated for financial accuracy and end-to-end process continuity before go-live.
Microsoft 365
Tenant separation involves migrating mailboxes, SharePoint, Teams data, and user identities. Access must be live early with no data loss.
Cloud Services & Infrastructure
Shared cloud services must be decomposed and stood up in the target environment. The carved-out entity's cloud strategy needs to be defined and operational before separation completes.
Data Carve Out
Financial records, customer data, vendor data, and transactional history all require separation. Data quality must be validated. Data transfers must be auditable. Sensitive data must be protected throughout.
Supply Chain & Operations
Supply chain systems tied to the business unit must be migrated and connected to the new entity's infrastructure. Business continuity here is non-negotiable.
Every hidden dependency becomes a failure point during separation.
Identify them before they break your timeline.
Protecting Business Continuity During Transition
Business continuity during an IT carve-out is the baseline because the carved-out entity still has customers, suppliers, and employees to serve during the transition.
A smooth separation depends on understanding how each team uses shared systems, what breaks if a dependency is disrupted even briefly, and how to sequence migration in a way that avoids operational impact.
Change management runs in parallel with the technical workstreams. End users need clarity on what is changing and when. Without that alignment, even a well-designed migration can create disruption.
WME structures every engagement around one requirement.
The carved-out business must be fully operational at the point of separation, without interruption to business continuity.
WME's Separation and Migration Approach
Discovery & Due Diligence
Map the full IT landscape. Identify every shared system, every dependency between source and target system, and every data flow crossing the separation boundary. This determines the real scope of the IT carve-out and whether the timeline is achievable.
Architecture & Migration Plans
Define the target environment. Build migration plans for each workstream, SAP carve-out, Data carve-out, Microsoft 365, and cloud services. The operating model for the new entity gets defined here.
Build, Configure & Test
Stand up the target environment. Migrate and validate master data against the source. Quality assurance runs at every checkpoint.
Change Management & Readiness
Prepare the business alongside the systems. End-user training, access provisioning, and support services are made active before go-live. Business processes are tested by the people running them.
Cutover & Day 1
Execute with precision. Migrated data verified. Data transfers confirmed. The carved-out business unit runs independently from minute one, on its own infrastructure, its own systems, its own support model.
Post-Separation Stabilisation
Support services run through a defined period after go-live. Issues are resolved before they affect business operations. The foundation is set for the entity’s longer-term digital transformation.
Carve-outs are not a variation of a standard migration. WME’s IT carve-out migration services are built around the complexity of separation events, the compressed timelines, entangled systems, and the business outcomes that depend on early readiness.
Managing Director-level involvement comes into delivery, not just pre-sales. From first-step due diligence through post-separation stabilisation, one team covers the full carve-out, including SAP carve-out, data carve-out, Microsoft 365, cloud services, and everything in between.
