That system you've been running for a decade? It was perfect when you had 15 employees. Now you have 80, and every workaround your team has invented is costing you money.
Legacy software isn't just old software. It's software that can no longer keep up with your business.
Warning Signs Your Software Is Holding You Back
Integration friction — New tools can't connect to your old system, so staff copy-paste data between applications daily.
Knowledge concentration — Only one or two people understand how it works. When they're on leave, problems wait.
Scaling pain — Performance degrades as your data grows. What took seconds now takes minutes.
Security gaps — The framework hasn't received security updates in years. You're one vulnerability away from a breach.
Feature paralysis — You've wanted new capabilities for years, but modifications are too risky or expensive.
The Hidden Costs of "If It Ain't Broke"
Legacy systems rarely feel broken—they just quietly drain resources:
- Staff time lost to manual workarounds
- Missed opportunities because the software can't support new processes
- Higher support costs as institutional knowledge walks out the door
- Growing technical debt that makes eventual migration even more expensive
Migration Strategies That Actually Work
Big bang replacement — Build the new system completely, then switch over in one coordinated effort. Risky but fast. Best for smaller, well-documented systems.
Incremental migration — Replace components piece by piece while the old system continues running. Slower but safer. Ideal for complex, business-critical systems.
Parallel operation — Run both systems simultaneously until the new one is proven. Most expensive but lowest risk.
Our Approach: Zero-Downtime Transitions
At CodeNexus, we specialise in legacy migrations that don't disrupt your operations:
- Comprehensive audit of existing system and dependencies
- Phased migration plan with clear rollback points
- Data migration with validation at every step
- Staff training before, during, and after transition
