Why Choose TechDocs for Legacy System Modernization?
Legacy systems are the silent killers of innovation. They are expensive to maintain, hard to hire for, and often full of security vulnerabilities. We specialize in bringing these systems into the modern era using low-risk, incremental strategies.
Whether it's migrating a VB6 app to .NET Core or moving a mainframe workload to AWS, we ensure your business logic is preserved while your infrastructure is future-proofed.
Services Included
Mainframe Offloading
Moving expensive MIPS workloads to x86 cloud instances.
UI/UX Refresh
Putting a modern web interface on top of ugly old green-screens.
Database Modernization
Migrating Oracle/SQL Server to open-source Postgres/Aurora.
DevOps Implementation
Adding CI/CD pipelines to previously manual deployment processes.
Our Approach
We avoid the risky "Big Bang" rewrite. Instead, we use the "Strangler Fig" pattern to gradually replace functionality piece by piece. This allows you to see value immediately and reduces the risk of catastrophic failure.
Our Process
Step 1: Discovery
Documenting every business rule in your current system.
Step 2: The "Wrapper"
Building an API layer around your legacy system to stop the bleeding.
Step 3: Strangulation
Systematically rewriting high-value modules one by one.
Step 4: Data Migration
Syncing data to the new database in real-time.
Step 5: Decommission
Turning off the old server once specific specific milestones are met.
