Outdated systems slow teams down. Square Root Solutions legacy app modernization services help upgrade old systems, reduce technical debt, and boost performance. We offer software transformation services built on 10+ years modernizing enterprise apps with proven scalability enhancement solutions that deliver results.
Let’s Discuss!
As a leading legacy application modernization company, Square Root Solutions and trusted modernization vendor in Ireland, known for delivering cost-effective reengineering with clear business continuity. As an Irish modernization firm, we’re based in Dublin with global project delivery.
We’ve completed 100+ legacy transformation projects with a legacy-to-modern conversion success rate 98%. Our process ensures 30% faster go-to-market with re-engineered apps. Our modernization roadmap supports clients in healthcare, finance, and logistics. Businesses choose us for deep experience in app development, fast results, and sector-led delivery.
We provide services across full modernization lifecycle using a modular modernization roadmap. Our experts deliver architecture reengineering, technical debt removal, and re-platforming legacy systems with scalable cloud-based refactoring, tailored scope upgrades, and a dedicated legacy- to-cloud task force delivering results in 4–12 weeks per module.
We begin with a legacy system audit to identify system bottlenecks with 100% transparency in audit findings. Our 7-day audit turnaround helps clients hire legacy software development company fast and prepare systems for complete modernization and performance improvement.
We lead with system re-architecture to break monolith into services, support horizontal scaling, and enable cloud burst handling. Clients experience 3x faster transaction processing, 99.98% uptime post-modernization, and future-ready cloud-ready and vendor-agnostic architecture for business growth.
We handle complete UI/UX revamp with mobile-responsive design, interactive wireframes, and WCAG-compliant UI for accessibility. Expect Figma-driven design handoffs, 100% browser and device compatibility, and up to 40% increase in user engagement after our design thinking workshops.
We perform legacy code cleanup and expose legacy logic via APIs with Swagger-based API documentation. The result: 80% code reusability post-refactor, 100+ reusable endpoints created, API gateway, interface contracts, and versioned API releases for modular systems.
Our cloud migration services deliver lift and shift to cloud with zero-downtime cloud migration using Terraform scripts and Kubernetes orchestration. Clients benefit from 100% infrastructure-as-code delivery, 40% faster deployment cycles, and multi-cloud and hybrid deployments supported.
We deliver QA automation with test automation suites, OWASP-compliant security tests, and staging environment simulation. Clients receive 95% test coverage guaranteed, 100% automated test cases for regression, and phased rollout testing for safer, high-confidence modernization rollouts.
Our legacy modernization process follows a 4-stage delivery framework built around agile sprints, risk-aware execution, and rollback plans. We combine discovery & technical feasibility check, cloud re-platforming, and zero-downtime rollout to achieve a 90%+ modernization success rate with measurable performance gains.
We begin with a 1–2 week discovery phase focused on legacy software upgrade lifecycle stages, architectural risks, and infrastructure gaps. Our team defines your app modernization workflow using system benchmarks, feasibility checks, and a structured legacy transformation and re-platforming roadmap.
We run weekly agile sprints with review checkpoints to build prototypes in phases. This stage enables safe refactoring and architectural redesign, reducing risk while validating usability and performance through a structured prototyping loop built into our app modernization workflow.
We ensure integration testing with zero-downtime rollout during go-live. Our phased deployment and change management approach follows risk-aware execution with rollback plans, guaranteeing uptime and system continuity while aligning modernized modules with legacy dependencies through tested workflows.
After launch, we offer performance tracking and SLA-driven monitoring. This step ensures system performance benchmarking, issue resolution, regression control, and platform optimization, maintaining operational health and extending app value post-upgrade through ongoing modernization lifecycle support.
We deliver industry-specific software modernization with vertical-focused app transformation strategies. Backed by 10+ industry-specific modernization case studies, we ensure 40% average cost savings, 70% faster user adoption, and GDPR and PCI DSS compliant modernization pipelines across legacy retail POS, Fintech compliance, and healthcare legacy HER, with a 96% on-time delivery rate.
