Application assessment and roadmap
Dependency inventory, workload decisions and a prioritised change backlog tied to business constraints.
App modernisation
Modernise legacy applications for safer releases, easier integration and scalable operations.
OVERVIEW
Modernise critical applications with business continuity in mind
When ageing applications constrain change, start with their business role, dependencies and operating risks. We assess what to retain, rehost, replatform, refactor or rebuild, then agree a staged roadmap rather than assume microservices are always the answer.
Baseline release lead time, incident rate and cost-to-change; use those measures to evaluate each wave. Discuss your modernisation priorities.
WHAT WE DELIVER
What we deliver
A roadmap, engineered change and an agreed operating scope - not a forced rebuild of every application.
Legacy refactoring and microservices
Target architecture and refactored components, with service boundaries only where they support the application.
APIs and integration
Versioned API contracts, data mappings and failure-handling rules for dependent systems.
Cloud-native engineering
Application changes and deployment configuration suited to the agreed cloud environment.
DevSecOps and release assurance
Build, test and deployment pipelines with agreed quality, security and rollback gates.
Experience redesign and support
Validated priority journeys and interfaces. Operate, monitor and improve applications against an agreed service scope.
ILLUSTRATIVE USE CASES
A staged modernisation journey
Illustrative use case: modernise a customer-facing service while retaining core transactions, using coexistence and agreed release gates.
1. Preserve the core process
Keep the legacy application serving agreed functions while our integration team establishes API contracts and a coexistence plan.
2. Modernise selected capabilities
Use an API layer and, where appropriate, Linkworks composable applications or cloud-native services. Agree data ownership and rollback triggers.
3. Assure each release
Quality Engineering validates critical journeys and regression; Cyber Security reviews access and application risks before operating handover.
LINKFIELDS IP & ACCELERATORS
Linkworks and modernisation delivery IP
Select IP against the application architecture, integration needs and release risks during discovery.
Linkworks
Microservices, REST APIs, composable UI, cloud-native solutions and DevSecOps for capabilities where ERP or CRM does not fit. It need not replace a suitable core platform.
testoriumz
Test management, low-code automation, AI root-cause analysis, dashboards and CI/CD integration support continuous release assurance.
Modernisation and assurance accelerators
The Modernisation & Integration Toolkit, Automated Testing & Release Assurance Packs and Cyber-Safe Delivery support the agreed scope.
Fit and licensing
Products are available by licence, subscription or SaaS, with or without a Linkfields services engagement. Discovery agrees product fit, reusable accelerator content and client-specific engineering.
SECURE BY DESIGN
From application estate to assured releases
Step 1: Assess
Map dependencies, user journeys and operating risks. Client application owners confirm business priorities, access and baseline measures; agree the assessment and roadmap.
Step 2: Design
Agree target architecture, migration waves, data controls and coexistence. The client approves acceptance criteria, rollback triggers and security requirements before build.
Step 3: Build
Engineer UX, APIs and automated pipelines. Prototype priority screens and test them with representative users; review code, configuration and access changes.
Step 4: Validate and hand over
Test migration, security and regression against the agreed gates. Record the release decision, rehearse rollback and transfer runbooks, monitoring and ownership to operations.
ACCEPTANCE & ACCOUNTABILITY
Evidence for each migration wave
A release decision should include dependency updates, regression results, security findings and rollback evidence - not just a completed build. Business owners accept priority journeys; technical owners record unresolved risks and operating readiness.
Compare release lead time, incidents and cost-to-change with the agreed baseline after each wave. Agree measurement periods and responsibility for the service after handover.

ENGAGEMENT & BUYER QUESTIONS
Plan the right engagement
Use Fixed Price for an agreed migration wave, or Time & Materials for estate discovery and evolving scope. A Dedicated Team supports sustained product engineering; Managed Service covers an agreed application operating scope. Outcome-Based work requires an evidenced baseline and agreed attribution.
