When should technology due diligence start?

Ideally before signing, with enough time to test management assumptions, review key contracts and identify material remediation or separation dependencies before they become fixed deal constraints.

What should a law-firm technology diligence review cover?

Typical scope includes infrastructure, cloud, identity, Microsoft 365, cyber, endpoints, networks, service management, application dependencies, document and practice-management platforms, suppliers, contracts and licensing.

What is the role of a TSA?

A Transitional Services Agreement defines services that one party continues to provide temporarily after completion. The technology workstream should define each service, ownership, service level, charging, dependency and explicit exit criteria.

Can Claranet support both buy-side integration and sell-side separation?

Yes. The same capabilities can be applied to acquisition integration, carve-out separation, divestment or merger programmes, with scope shaped around who owns the target-state platforms and retained services.

Can you migrate Microsoft 365 and identity as part of the deal?

Claranet provides Microsoft 365 deployment and migration services and can incorporate identity, endpoint, network, cloud and security work into the wider integration programme.

Do you replace specialist legal application integrators?

Not necessarily. The model can coordinate with specialist owners of document-management, practice-management or other legal applications while Claranet takes accountability for the surrounding workplace, infrastructure, security and service-management layers.

Technology due diligence, TSA & integration for law-firm M&A

The technology workstream has three jobs: surface risk before signing, keep the firm operating on Day 1, and create a credible path out of transitional complexity.

Do not let technology become the reason a legal transaction slows down

Law-firm M&A concentrates identity, document management, client data, Microsoft 365, networks, security and line-of-business applications into one of the most time-sensitive workstreams in the deal.

Before signing, technology diligence needs to distinguish ordinary technical debt from issues that change deal economics or execution risk. We assess infrastructure, cloud, cyber posture, licensing, suppliers, application estates, support capability and the dependencies that will matter during integration or separation.

Once the transaction moves forward, we convert those findings into a Day 1 and TSA plan. That means defining which services must continue, who owns them, what data and identities need to move, where temporary dependencies sit, and what “exit” actually means for each service.

Claranet can then support delivery across Microsoft 365, identity, network, cloud, endpoint, security, service desk and migration workstreams. The objective is not a theoretical integration blueprint: it is a sequenced programme that protects fee-earner productivity and client service while the estate changes around them.

Find the technology risks that can change deal value

Technology diligence should tell the deal team what matters commercially: hidden cost, security exposure, unsupported platforms, contractual constraints, duplicated capability and dependencies that will make integration or separation harder.

We translate technical findings into a prioritised view for CIO, COO, corporate-development and PE stakeholders, with clear ownership and an estimate of the work that sits behind each material risk.

Infrastructure, cloud, network, Microsoft 365, endpoint and service-management assessment.
Cyber posture, material vulnerabilities, control maturity and incident history review.
Application, document-management, practice-management and data dependency mapping.
Supplier, licensing and contract review to identify transfer, termination and stranded-cost risk.

Scope technology due diligence

Build a TSA and Day 1 plan that operators can actually execute

A TSA is only useful if each service has a clear owner, measurable service expectation and an exit route. We help map the services that must continue across signing, completion and separation, including the technical and operational dependencies that are easy to miss during deal pressure.

For law firms that can include identity, email, document management, secure file transfer, service desk, networks, endpoint management, security monitoring and access to shared business systems.

Day 1 minimum viable service definition for users, offices and critical client workflows.
TSA service catalogue, ownership, service levels, charging assumptions and governance.
Dependency map covering data, identity, connectivity, applications, suppliers and support teams.
Exit milestones and risk tracking so temporary arrangements do not become permanent architecture.

Map your target operating model

Deliver the migrations, separations and integrations behind the deal

After the planning comes the operational work. Claranet can provide programme and technical delivery across the core infrastructure and workplace layers, coordinating with legal-application owners and retained teams where specialist systems sit outside our scope.

We use phased cutovers, rollback planning and explicit service ownership to reduce disruption to lawyers and clients. The same delivery model can support acquisition integration, divestment separation or a broader platform-consolidation programme.

Microsoft 365 tenant migration, identity consolidation and endpoint transition.
Network, connectivity, cloud and security integration across offices and entities.
Data migration and service cutover planning with controlled validation and rollback.
Post-deal rationalisation of suppliers, licences and duplicated managed services.

Plan the integration workstream

Have a transaction where technology cannot be allowed to drift?

Bring Claranet into the workstream early enough to surface deal risk, define Day 1 and TSA dependencies, and turn the integration plan into executable delivery.
