The following discussion illustrates a project that is well suited to the capabilities of an independent consultant in the Umbrex Private Equity Practice. This is an illustrative example. Umbrex consultants adapt their methodology, timeline, and deliverables to the specific needs of each client.
1) Client Situation
The client operated across a multi-product private equity platform and required support with Technology Carve-Out And Data Migration in the context of Private Equity. Stakeholders included Mega/Large-Cap Private Equity Buyout Firms running global carve-outs with complex Microsoft 365 and ERP landscapes; Mid-Market & Lower Mid-Market Private Equity Sponsors disentangling IT for buy-and-build platforms with first institutional processes; Growth Equity Investors (Private Equity) executing targeted separations with lean IT; Private Equity Operating Partners & Value Creation Teams standardizing TSA exit playbooks and cyber controls across the portfolio; and PE-Owned Portfolio Companies standing up NewCo IT under TSA constraints. The diagnostic we conducted surfaced separation design, identity/network disentanglement, and data migration risks that jeopardized Day-1 continuity, TSA exit timelines, and cyber posture:
- Incomplete application, data, and infrastructure inventory
- CMDBs were outdated; shadow IT (SaaS, shared file shares) was prevalent; integration maps between ERP, CRM, PLM, WMS, and data warehouse were undocumented; data domains (customer, supplier, SKU, employee) lacked authoritative owners.
- Identity and tenant entanglement
- Single Microsoft 365/Entra ID tenants served multiple business units; legacy on-prem Active Directory trusts and shared domains complicated split; OAuth app consents, service principals, and conditional access policies were not cataloged; privileged access lacked a separation plan.
- Network and security interdependencies
- Shared networks, SD-WAN, and VPN concentrators lacked segmentation; DNS/DHCP were centralized; logging flowed to a single SIEM; endpoint EDR/XDR policies and MDM profiles were common across entities; zero-trust policies were not scoped for NewCo.
- Email and collaboration complexity
- Cross-tenant mail flow, calendar free/busy, shared Teams/SharePoint sites, and OneDrive ownership were intertwined; domain transfers and MX/SPF/DKIM/DMARC changes were not sequenced; litigation holds and eDiscovery constraints were unplanned.
- Licensing and contract constraints
- Enterprise agreements for Microsoft, Salesforce, SAP/Oracle, network/security, and SaaS tools were consolidated under Seller; novation/assignment clauses, minimum seat commits, and true-up schedules limited carve-out options.
- Data migration and residency risks
- PII/MNPI classification was inconsistent; data residency obligations (GDPR/UK GDPR and sectoral rules) were not mapped; archival vs. migration decisions were unclear; encryption and key management (KMS) responsibilities were ambiguous.
- TSA exit plan not engineered
- TSAs lacked service definitions, SLAs, credits, and SME access; interim tooling and double-run budgets were not set; exit gates and “no later than” dates were undefined.
- Underperforming KPIs
- Missed readiness gates; high defect rates in trial migrations; access provisioning lag at Day-1; change freezes not respected; endpoint compliance drift; mailbox and SharePoint migration backlogs; TSA burn beyond plan; and limited visibility to integration failures post-cutover.
2) Project Objective
The primary objective focused on defining the target IT stack, disentangling networks and identities, standing up interim tools, executing data migration waves, and planning TSA exits to minimize disruption and cyber risk—delivering a clean Day-1, predictable cutovers, and accelerated independence for NewCo.
Secondary objectives included:
- Establishing a complete inventory of applications, integrations, infrastructure, and data with authoritative ownership and lineage.
- Designing a target and interim architecture (keep/clone/replatform/retire) anchored by identity-first security (SSO/MFA, PAM, SoD) and zero-trust segmentation.
- Building and rehearsing cutover, rollback, and command center runbooks for mail/collaboration, ERP/CRM, file shares, and data platforms.
- Executing tenant splits and data migrations (Exchange/OneDrive/SharePoint/Teams; file shares; ERP/CRM records; data lake/warehouse tables) with validation and defect management.
- Implementing endpoint management, EDR/XDR, DLP, logging/SIEM, and backup/DR aligned to CIS/NIST controls and audit evidence needs.
- Negotiating TSA scope with SLAs/credits and SME access; sequencing capability stand-up and license/contract novations; tracking exit gates.
- Standing up ITSM, change control, and incident response to stabilize Day-1 through hypercare; embedding dashboards and evidence repositories for board/lender readiness.
3) Methodology and Approach

- Architecture & inventories
- Application and integration inventories; environment lists; AD/Entra ID/Okta tenants and domains; mail/Teams/SharePoint sites; file share maps; network topology (SD-WAN/VPN/firewalls); DNS/DHCP configs.
- Identity & access
- Role/entitlement catalogs; conditional access policies; PAM/privileged account lists; SoD matrices; OAuth apps and service principals; certificate/key stores.
- Contracts & licensing
- Enterprise agreements (Microsoft, Salesforce, SAP/Oracle, security tools); SaaS contracts; novation/assignment clauses; support SLAs; true-up schedules; minimum commits.
- Data & integrations

- Security & operations
- EDR/XDR and MDM coverage; SIEM sources and use cases; backup/DR inventories; incident response runbooks; change calendars; ITSM KBs/runbooks.
- Collaboration & messaging
- Exchange mailboxes and sizes; OneDrive/SharePoint sites/ownership; Teams structure and external access; domains and DNS records (MX/SPF/DKIM/DMARC); eDiscovery/litigation hold lists.

9) Industry Insights
- Identity-first separation reduces risk
- Cross-tenant planning, SSO/MFA, PAM, and SoD determine Day-1 security and usability; mail and collaboration follow identity patterns—treat them as a package.
- Data migration is a factory, not a single weekend
- Wave planning, reconciliation scripts, and business sign-offs prevent surprises; dbt tests and checksums catch defects early; archival vs. migration decisions protect timelines.
- DNS and mail are “small hinges” with big doors
- MX/SPF/DKIM/DMARC timing and domain transfers drive user-visible success; coexistence and forwarders reduce disruption; plan for eDiscovery and legal holds.
- Vendor and license constraints shape architecture
- Novation rights, minimums, and true-ups often dictate keep/clone choices more than technology; bridge licenses and concessions reduce TSA dependence.
- Zero trust is pragmatic in carve-outs
- Segment networks early, enforce device compliance and conditional access, and centralize logging; it contains risk while teams operate under stress.
- ITSM and command centers turn plans into execution
- Mock weekends with defect injection and a staffed Day-1 command center cut MTTR and protect business continuity; hypercare dashboards drive stabilization.
- What “good” looks like
- A documented separation blueprint; identity and tenant migration playbooks; segmented networks and enforced cyber controls; rehearsed data migration waves with reconciliation; coherent interface switch plans; licensed and supported applications; TSA exits with SME access and credits; Day-1 command center and hypercare with exit criteria; and audit-ready evidence for boards and lenders.
- Near-term watch points
- AD forest splits and legacy trusts, certificate/key expirations, OAuth and app consent sprawl, shared Teams/SharePoint ownership, EDI partner readiness, contract novation lead times, TSA SME availability, endpoint compliance drift, and quarter-end change freezes. Early readiness gates and escalation keep the program predictable.
Implications for clients we served included enabling Mega/Large-Cap Private Equity Buyout Firms to execute complex technology carve-outs with predictable Day-1 performance and cyber posture; supporting Mid-Market & Lower Mid-Market Private Equity Sponsors to institutionalize TSA exit and migration factories; equipping Growth Equity Investors (Private Equity) to deliver targeted separations with lean teams; guiding Private Equity Operating Partners & Value Creation Teams to standardize identity, data, and TSA playbooks; and providing PE-Owned Portfolio Companies with clear checklists, runbooks, and dashboards that stabilized operations while accelerating independence.
