Cloud Migration
Your 15-year-old application holding you back? We migrate it to modern
cloud safely and gradually.
Challenges We Solve
Legacy systems mean high costs and loss of competitiveness
System Can't Scale
Desktop application or on-premise server can't grow with your business. Each new user means additional hardware.
Maintenance Costs Fortune
Older technologies (VB6, Delphi, FoxPro) require specialists who are expensive and hard to find.
Security is a Risk
Old systems no longer receive security patches. You're vulnerable to attacks and GDPR is a nightmare.
Integration Doesn't Exist
Your system has no API. You can't connect it with CRM, e-commerce or modern tools. You copy data manually.
Our Solution
Complete migration to modern cloud architecture
Cloud-Native Architecture
We migrate to Azure, AWS or Google Cloud using microservice architecture and containers.
- Auto-scaling based on load
- High availability and redundancy
- Global availability
- Pay only for resources used
API-First Approach
We create modern REST/GraphQL APIs for easy integration with any systems.
- RESTful or GraphQL API
- OAuth 2.0 authentication
- API documentation (Swagger/OpenAPI)
- Request throttling and monitoring
Backend Modernization
We rewrite legacy code to .NET Core or Node.js.
- .NET Core, Node.js
- Microservices or modular monolith
- Event-driven architecture
- Command Query Responsibility Segregation
Modern Frontend
New web and mobile UI built on React or Angular.
- Responsive design
- Progressive Web App (PWA)
- Real-time updates
- Mobile device optimization
How We Work
First we understand your processes. Then we propose solutions.
Discovery & Audit
We analyze your existing system, code, database and business processes. Identify critical points and propose migration strategy.
Architecture & Plan
We design target cloud architecture, technologies and detailed migration plan with milestones.
Pilot Migration
We migrate selected module or feature as proof-of-concept. Test and validate approach.
Gradual Migration
We migrate system module by module. Runs parallel with legacy system, gradual migration with minimal operational impact.
Data Migration
We transfer historical data, test integrity and validate business logic.
Go-Live & Support
We switch to new system, monitor, quickly resolve issues. Provide training and documentation.

Case Study
Helvetia: Migration from Visual Basic to .NET and Azure
HELVETIA
E-commerceChallenge
International e-commerce with natural health supplements operated a 15-year-old desktop application in Visual Basic. The system wasn't scalable, didn't allow integration with modern tools, and maintenance costs were rising.
Solution
We migrated the legacy Visual Basic application to modern .NET Core with microservice architecture hosted on Azure. Created REST API for integration with all systems and new responsive web interface.
Frequently Asked Questions
What happens to our historical data during migration?
We migrate all historical data including structure and relationships. Process includes: export from legacy database, transformation to new schema, validation of data integrity and consistency, and test import. Original data remains untouched as backup. Average data migration for 100GB+ database takes 2-4 weeks.
How do you handle rollback if migration fails?
We use blue-green deployment strategy - new system runs in parallel with old one. You can switch back to legacy system anytime. Only when new system is fully tested and stable (typically 2-4 weeks of operation), we shut down old infrastructure. Data is synchronized bidirectionally during transition period.
Do you support migration from Oracle, SQL Server or other databases?
Yes, we migrate from Oracle, SQL Server, MySQL, PostgreSQL, Sybase, DB2, FoxPro and others. We use Azure Database Migration Service or AWS DMS for automation. For complex migrations (stored procedures, triggers, custom functions) we rewrite logic to application layer or target database.
Can you migrate Visual Basic 6, Delphi or FoxPro applications?
Yes, we have experience migrating VB6, Delphi, FoxPro, PowerBuilder and other legacy technologies. We rewrite most business logic to .NET Core or Node.js. Desktop UI is converted to modern web interface (React/Angular) or progressive web app. We preserve same functionality with better user experience.
