Technologies
Modernizing complex enterprise technology portfolios.
ResQSoft modernizes complete business systems, not isolated programming languages. Legacy applications often combine old platforms, databases, batch jobs, reports, interfaces, screens, and decades of business rules.
Legacy Source Environments
Technologies we commonly modernize.
The list below is not exhaustive. Many enterprise portfolios contain specialized tools, uncommon platforms, proprietary frameworks, and mixed technology stacks. The important question is not merely what language the system uses, but whether the business behavior can be understood, preserved, and moved into a maintainable modern architecture.
Mainframe & legacy languages
- ANSI COBOL
- IBM COBOL
- Micro Focus COBOL
- Natural / Adabas
- ADR Ideal / Datacom
- JCL and batch environments
Client/server & 4GL
- Oracle Forms
- PowerBuilder
- Visual Basic
- FoxPro
- SilverStream
- Forte
Model-driven systems
- CA Gen (COOL:Gen)
- AllFusion Gen
- Pacbase
- Telon
- IEF
- Other generated-code environments
Legacy Java & web
- Struts
- JSP-heavy architectures
- EJB
- Older servlet frameworks
- Older Spring applications
- WebLogic and WebSphere-era architectures
Databases & data stores
- DB2
- Adabas
- Oracle
- Datacom
- SQL Server
- Model 204 / M204
- Flat files and indexed file systems
Modern Target Architectures
The target is not merely a newer language.
A modernization target should be selected based on the customer's architecture standards, staffing, operational model, security requirements, and future business goals. ResQSoft commonly delivers modular web applications, Java back ends, Angular or React front ends, .NET applications, cloud-ready architectures, and microservice-oriented designs where they are appropriate.
Not every system should become microservices. Not every system needs cloud deployment on day one. The architecture should solve the business and operational problem rather than follow a fashion.
Common modern targets
- Java / Spring Boot services
- Angular front ends
- React front ends
- .NET / C# applications
- REST APIs
- Modern SQL databases
Architecture options
- Modular web applications
- Microservices where appropriate
- Cloud-ready deployment
- Container-ready architectures
- API-enabled integration
- Analytics and AI-ready foundations
Systems, Not Languages
Technology lists are only the starting point.
A legacy portfolio is usually more than COBOL, Java, Oracle Forms, or PowerBuilder. It includes database design, batch processing, reports, security models, interfaces, operating procedures, and years of business-rule accumulation.
ResQSoft's job is not simply to convert syntax. It is to preserve business value while creating source code, architecture, and delivery practices the customer can carry forward.
Technology Risk
The software may still work. The ecosystem may not.
Many legacy systems continue to process transactions successfully. The risk emerges around staffing, security, integration, cloud adoption, deferred enhancement backlog, and long-term maintainability.
Shrinking talent pools
Systems become risky when the people who understand them retire, leave, or become difficult to recruit and retain.
Integration pressure
Older systems often struggle to support modern APIs, analytics platforms, identity services, digital channels, and data-sharing requirements.
Future capability limits
A system may still run but be poorly positioned for automation, cloud adoption, AI-enabled business capabilities, or rapid delivery of new requirements.
