Facile Technolab modernizes legacy enterprise applications - Classic ASP, ASP.NET Web Forms, .NET Framework, WCF, ColdFusion, and PHP - to modern ASP.NET Core and Azure. We specialize in phased modernization that keeps production systems running throughout. 10+ years, 31 verified Clutch reviews, clients across the US, Australia, and Europe.
Most of our modernization engagements start with one of these technology situations:
VBScript, COM components, and IIS-native applications migrated to modern C# and ASP.NET Core. The most complex migration type - requires full rewrite with careful COM dependency assessment.
ASP.NET MVC, Web Forms, or WCF applications modernized to ASP.NET Core running on the current .NET 8 LTS release. Microsoft's .NET Upgrade Assistant supports much of this path.
Page lifecycle-based Web Forms converted to Razor Pages, MVC, or Blazor. Phased migration using the Strangler Fig pattern keeps production systems live during conversion.
Windows Communication Foundation services migrated to REST APIs, gRPC, or CoreWCF depending on client constraints. Includes authentication, contract, and binding migration.
CFML-based enterprise applications migrated to C# and ASP.NET Core. We have a delivered case study in this specific migration.
Enterprise PHP applications migrated to the Microsoft stack where the organization has standardized on .NET and Azure.
Legacy systems don't fail evenly across industries. In operations-heavy environments where software runs manufacturing lines, patient workflows, compliance reporting, or financial transactions, the cost of keeping an ageing system running grows faster than in lighter contexts, and the risk of cutover is higher. Here is how modernization typically presents in the industries we work with most.
Legacy patient management systems, HIPAA-era portals, and on-premise clinical tools built on Classic ASP, Web Forms, or older .NET Framework are increasingly difficult to maintain and extend. Compliance requirements (HIPAA, HL7, FHIR) have also evolved - applications built in 2005 were not designed for current standards. We modernize healthcare systems with a phased approach that keeps patient-facing and clinical operations running throughout.
Financial applications built on legacy .NET Framework or Classic ASP often carry undocumented business logic - interest calculation engines, compliance reporting rules, transaction validation - that is too risky to rewrite without careful mapping. Our FinTech modernization work includes a case study of a lending platform migrated from a decade-old stack to ASP.NET Core and Azure, preserving all business rules with zero downtime.
Manufacturing operations software - production scheduling, MES integrations, inventory management, quality reporting - is often the oldest software in a business because it works and nobody wants to touch it. WCF services, SOAP APIs, and VB6 COM components are common in this space. We specialize in modernizing manufacturing systems without disrupting production operations.
Engineering firms often run project management, document control, and tender management platforms built on older ASP.NET stacks. These systems are deeply embedded in daily operations but expensive to maintain as the underlying frameworks fall out of support. We have worked with engineering clients including Summers Engineering in Australia on exactly this kind of operational system modernization.
Construction companies running project management, job costing, and subcontractor management on legacy systems face growing pressure from cloud-first competitors. The challenge is that these systems often integrate with accounting platforms (MYOB, Xero) via legacy API patterns that need to be preserved during modernization. We assess these integration dependencies upfront before any migration begins.
Technology companies that have standardized on Microsoft stack sometimes inherit or acquire Classic ASP, Web Forms, or older SaaS products that don't fit their current architecture. Internal tooling built years ago by developers who have since left is a common scenario. We handle codebase takeover, assessment, and modernization for IT companies managing inherited .NET systems.
Student portals, LMS platforms, and administrative systems built on older .NET stacks are a common modernization request from education providers - particularly those that self-hosted systems that are now difficult to maintain and can't be moved to cloud without a modernization project. We assess and migrate these systems with an emphasis on data integrity and uptime during student-facing term periods.
Startups that acquired or inherited a legacy codebase - through acquisition, founder departure, or a v1 build that outgrew its stack - need modernization that preserves the product while enabling the team to move fast. We run discovery-first assessments that separate "must fix now" from "can improve incrementally" so startup budgets go where they have most impact.

This agility, with modernized systems that enable rapid adaptation to changing business needs and support growing workloads, is designed to ensure future growth and keep businesses competitive and efficient.
Legacy system upgrade reduces risks on security and addresses vulnerabilities in ensuring your systems are secure against cyber threats. Modern systems will help to keep your business data safe and compliant.
It saves operational cost since it eliminates technical debt and minimizes the expensive maintenance of legacy systems hence resources are employed efficiently.
Modernized systems provide faster processing, enhanced reliability, and maximum usage of resources. It leads to better utilization by users and overall efficient systems.
Software modernization is easy to integrate with new tools and APIs that enhance functionality while ensuring proper interoperability for smooth communication between systems and data flow.
Modernizing the software will transform your legacy system into a solid base which will be used as support for long-term success within your business.
We follow a structured, low-risk delivery process built around one principle: your production system stays live throughout. Every modernization engagement starts with understanding what you have before touching a line of code — because the surprises in legacy systems always surface during discovery, not development, and it's better to find them early.
We review your existing codebase, map dependencies (COM objects, third-party integrations, database connections), identify undocumented business logic, and assess your infrastructure. You receive a detailed report covering migration complexity, risk areas, recommended approach, and a realistic timeline and cost estimate — before any development commitment is made.
Based on the assessment, we design the target architecture and choose the right migration pattern for your application - Strangler Fig for large systems that need to stay live, parallel rebuild for smaller well-scoped applications, or component-by-component for COM-heavy codebases. We define the phasing, agree on acceptance criteria for each module, and establish the integration and testing strategy before development begins.
Development runs in two-week sprints with working, deployable output at the end of each sprint. Migrated modules go to production incrementally - you're not waiting months for a single cutover. Each phase is tested against the original system's behaviour before going live, and the legacy system remains available as a fallback throughout the migration period.
At completion you receive full code ownership, architecture documentation, deployment runbooks, and a knowledge transfer session with your internal team. We provide a post-launch support period as standard - typically 30–60 days - to stabilise the modernized system in production before transitioning to your ongoing maintenance arrangement.

What is the difference between software modernization and a rewrite? Modernization preserves and transforms existing business logic - it's a phased process that keeps production systems running while gradually converting components. A rewrite discards the existing codebase and builds from scratch, which is faster to scope but carries more risk for complex enterprise systems with years of accumulated business rules. Most of our engagements use a phased modernization approach (Strangler Fig pattern) rather than a full rewrite, because it allows continuous validation and avoids a single high-risk cutover. A full rewrite is occasionally the right answer - typically when the legacy codebase is so poorly structured that incremental improvement is not viable.
It depends entirely on the legacy platform, application size, and complexity. A small Classic ASP application (under 20 pages) might take 6–10 weeks. A mid-size .NET Framework MVC application typically takes 3–6 months. A large enterprise Web Forms or WCF system with complex integrations commonly takes 6–18 months. The most reliable way to scope a modernization project is a structured assessment phase - we review the codebase, identify dependencies, and provide a detailed timeline before any development begins.
In most cases yes. The Strangler Fig pattern allows phased migration where the legacy system and the modernized system run simultaneously, with a reverse proxy routing traffic to the appropriate application. New or migrated functionality goes to the modern system; unmigrated sections remain on the legacy system. This approach is standard for Classic ASP, Web Forms, and WCF migrations where operational continuity is the primary constraint.
Yes. Our core specialization is Microsoft-stack modernization - Classic ASP, ASP.NET Web Forms, ASP.NET MVC, .NET Framework, and WCF to ASP.NET Core, Blazor, and Azure. We also modernize ColdFusion and PHP applications to ASP.NET Core where the organization has chosen to standardize on the Microsoft stack. We don't modernize systems to non-Microsoft targets - if you're looking for PHP-to-Node.js or ColdFusion-to-Ruby migrations, we're not the right fit.
Legacy software modernization services improve outdated applications so they meet modern requirements for security, performance, maintainability, and scalability—often by modernizing architecture and moving to platforms like ASP.NET Core and Azure.
Our assessment covers: codebase inventory (technology versions, LOC, module structure), dependency mapping (third-party libraries, COM objects, external integrations), database analysis (platform, schema quality, data volume), risk identification (undocumented logic, security vulnerabilities, unsupported dependencies), and a recommended migration path with phased timeline and cost estimate. For Classic ASP and COM-heavy applications, the COM dependency assessment is the most critical component - it's what most determines migration complexity and timeline.
Software modernization helps businesses enhance system performance, improve security, enable scalability, leverage new features, and adapt to changing business requirements.
Software modernization offers benefits such as increased productivity, reduced maintenance costs, improved user experience, enhanced integration capabilities, and future-proofing your software.
Facile Technolab carefully assesses and plans for system integrations during the modernization process to ensure smooth transition and continuity of business operations.
Yes, AI enablement often becomes easier after modernization. Once the platform is cloud-ready and data flows are improved, AI features such as document extraction, anomaly detection, and intelligent search can be integrated safely.
