Many businesses today still rely on legacy software—applications built years or even decades ago—that are critical to daily operations. However, outdated systems can slow down innovation, increase IT costs, and expose organisations to cybersecurity risks. That’s where legacy software modernization development services come in. Modernisation allows companies to upgrade old systems into scalable, secure, and efficient platforms that align with today’s digital-first economy.
According to a Gartner report, by 2027, nearly 50% of enterprises will need legacy software modernization to remain competitive. This trend is driving demand for specialised agencies, developers, and consultancies offering end-to-end solutions.
Why Modernize Legacy Software?
- High Maintenance Costs – Running outdated systems can consume up to 70–80% of an IT budget.
- Cybersecurity Risks – Legacy applications often lack modern security protocols, making them prime targets for cyberattacks.
- Lack of Integration – Old software struggles to integrate with cloud, AI, or IoT solutions.
- Talent Shortage – Fewer developers are skilled in older languages like COBOL, VB, or Delphi.
- Regulatory Compliance – Industries like healthcare, finance, and manufacturing need modernization to comply with HIPAA, GDPR, or SOC 2 standards.
Legacy Software Modernization Approaches
Agencies and consultancies typically recommend a tailored approach:
- Replatforming – Migrating applications to cloud-based platforms (AWS, Azure, GCP).
- Refactoring – Rewriting parts of code for better scalability and performance.
- Microservices Architecture – Breaking monolithic applications into modular microservices for agility.
- Agile Transformation – Using Agile methodologies to ensure faster, iterative modernization.
- Complete Redesign – Building new systems while maintaining existing workflows.
Modernization with Microservices & Agile Consulting
- Microservices: Enable independent scaling of business functions, reducing downtime and improving flexibility.
- Agile Transformation Consulting: Ensures modernization projects deliver value quickly with continuous updates and reduced risks.
Example: A manufacturing firm in the USA modernised its ERP with microservices and reduced IT downtime by 35%, while saving $1.2 million annually in maintenance costs.
Key Services Offered by Modernization Agencies
- Legacy software assessment & roadmap design
- Cloud migration & DevOps enablement
- API integration with modern SaaS platforms
- UI/UX redesign for legacy applications
- End-to-end modernization consultancy
Cost of Legacy Software Modernization
The cost depends on project complexity, size, and industry needs:
- Small applications: $50,000 – $150,000
- Medium-scale ERP/CRM modernization: $200,000 – $500,000
- Enterprise-level systems: $1M+
However, studies show businesses can achieve an ROI of 200–400% within 3–5 years due to lower maintenance costs, better performance, and improved scalability.
Industries Leading in Modernization
- Banking & Finance – Digital-first banking requires fast, secure systems.
- Healthcare – Compliance-driven modernization (HIPAA).
- Manufacturing – Industry 4.0, IoT integration.
- Retail – Omnichannel systems & AI-driven analytics.

Future of Legacy Modernization
- AI & Automation: Tools that auto-convert legacy code to modern languages.
- Low-Code/No-Code Platforms: Faster application modernization.
- Cloud-Native Systems: Becoming the default for all modernization projects.
By 2030, the global application modernization services market is projected to reach $50 billion, driven by cloud, AI, and cybersecurity requirements.
