Modernization
Legacy System Modernization
We modernize legacy systems that have outlived their technological lifecycle but that your company still needs to keep running. We use incremental refactoring and data migration so the transition to a modern architecture doesn't disrupt your day-to-day operation.
Why Choose This Solution
Migration with no downtime
Incremental migration strategies that keep the legacy system operational during the transition.
Staged refactoring
We don't rewrite everything at once: we identify the highest-risk modules and modernize them first.
Database migration
Safe migration of historical data to modern engines, with integrity validation at every step.
Compatibility APIs
Compatibility layers that let new and old systems coexist during the transition.
Reduced technical risk
Eliminate dependency on unsupported technology, obsolete languages, or scarce specialized staff.
Frequently Asked Questions
How do I know if my system needs modernization?
+
Clear signs: technology with no official support, difficulty finding developers who know it, inability to integrate with modern systems, or rising maintenance costs.
Do operations need to stop during migration?
+
Not in most cases. We use incremental strategies (strangler fig pattern) where the new and old systems coexist until the transition is complete.
What happens to historical data?
+
It's migrated through validation processes that guarantee integrity — no data is lost or corrupted in the process.
How long does it take to modernize a legacy system?
+
It depends on size and complexity: a narrow module can be modernized in 4-8 weeks; a complete, critical system can take several months in planned phases.
Can you modernize systems in any language or technology?
+
We work with most common legacy stacks (old PHP, .NET Framework, legacy Java, VB, systems with proprietary databases), migrating toward modern, maintainable architectures.
Can you modernize just the frontend while keeping the legacy backend?
+
Yes, it's a valid strategy: we modernize the layer with the most user impact first and migrate the backend in a later phase.
What happens to integrations that depend on the legacy system?
+
We map all dependencies before migrating and build compatibility layers so they don't break during the transition.
How do you avoid losing functionality during modernization?
+
We thoroughly document current behavior (including undocumented behavior) before rewriting, and validate with regression testing.
