We design secure, resilient and cost-effective migration paths for enterprise software — from monolith breakdown and legacy modernisation to cloud native replatforming, data migration and automated DevOps. Our senior engineers partner with your leadership to reduce risk, accelerate value and unlock future capability.
Fast facts for senior stakeholders — what we deliver and how we measure success.
Our modernisation approach is backed by real-world results from enterprises who've successfully transformed their legacy systems.
Assemblysoft combines strategic assessment, pragmatic engineering and automated delivery to migrate and modernise systems while preserving business continuity. We focus on minimum viable change with maximum business outcome.
Risk-led discovery, dependency mapping, cost modelling and migration roadmapping. We analyse your technical debt, integration points, and business-critical workflows.
Deliverables: Executive report, TCO analysis, migration plan
Identify bounded contexts, create domain-aligned services and build incremental strangler patterns to safely extract functionality without disrupting operations.
Pattern: Strangler Fig, Domain-Driven Design
Containerisation, serverless for burst workloads, managed platform adoption (AKS, App Service, Functions) and secure networking with Azure best practices.
Platforms: Azure Kubernetes, App Service, Functions
We migrate data with minimal downtime using staged strategies, change data capture and resilient ETL. Integrations are refactored to cloud-first patterns and secured with modern identity and API management.
Automated pipelines, shift-left testing, infrastructure as code and progressive delivery (blue-green, canary) to make releases safe, repeatable and auditable.
Based on our experience modernizing .NET legacy systems for enterprises, here are the most common scenarios we help solve.
ViewState bloat, server controls, tightly coupled UI logic, no cross-platform support
Single deployment unit, database coupling, team bottlenecks, scaling limitations
On-premises licensing costs, manual backups, global latency, limited scalability
SOAP complexity, Windows-only hosting, poor mobile support, no cloud-native patterns
Custom auth tables, password management risk, no SSO, limited MFA
FTP deployments, manual testing, no rollback strategy, deployment anxiety
Our phased approach ensures business continuity while progressively transforming your systems.
Deep-dive technical audit, stakeholder interviews, cost-benefit analysis. We create a detailed migration roadmap with risk mitigation strategies and business case.
Azure landing zones, network architecture, identity integration, DevOps pipelines, monitoring infrastructure. Everything needed for secure, compliant cloud operations.
Start with a non-critical service or feature. Validate approach, refine processes, train teams and demonstrate quick wins to build organizational confidence.
Phased migration of services using strangler fig pattern. Each phase is fully tested, monitored and validated before moving to the next. Business continues uninterrupted.
Cost optimization, performance tuning, security hardening and knowledge transfer. We ensure your team can operate and evolve the modernized platform independently.
We leverage Microsoft's ecosystem and cloud-native technologies to deliver secure, scalable modernisation solutions.
Cloud-native APIs, microservices and intelligent automation.
Refactoring, replatforming and pragmatic redesign for cloud readiness.
Explore our full set of cloud modernisation services and pillars of delivery.
Assemblysoft aligns our cloud modernisation approach with Microsoft guidance and tooling to reduce migration risk and accelerate business value. We leverage Azure platform services, Azure Migrate, Azure Well-Architected principles, GitHub and Azure DevOps for secure, repeatable delivery.
This alignment means your migration uses proven Microsoft patterns and toolchains trusted by Fortune 500 companies, backed by observable metrics and continuous improvement.
