Systems degrade silently: hard-to-analyze code, regressions, weak testing, tightly coupled modules
New features slow down, releases are risky, and the fear of change grows
Budgets are spent on supporting critical features, not modernizing and moving forward
Operational knowledge is kept in the heads of a few key experts, not in documentation
Legacy support by Corsac protects stability, compliance, and tomorrow’s revenues
With over 18 years of modernization experience, Corsac offers legacy software support for complex platforms where downtime isn’t acceptable. Through deep analysis and senior engineering oversight, we stabilize systems and guide safe, gradual improvement.

Let us help you rebuild what’s holding you back.
Corsac specializes in legacy system support when modernization is too risky, the system cannot be replaced right now, or your business prioritizes predictability over transformation. Comprehensive analysis and senior engineering involvement help keep the system healthy.
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
We conduct an in-depth analysis of architecture, dependencies, risks, and support gaps. This evaluation provides insights that direct further efforts in stabilization, cost control, and wise maintenance.
We restore system knowledge by recreating documentation, identifying core components, and capturing essential business logic. This helps create a clear and supportable system that no longer depends on a few key experts.
Enable system visibility through logging and monitoring, and implement alerting to detect and resolve issues early
Determine unsupported or outdated components to prioritize security fixes or apply compensating controls
Establish a clear incident response based on root-cause analysis to prevent repeated failures
Stabilize release and support processes to make updates safer and more predictable
Replace reactive firefighting with proactive support through continuous monitoring of system performance and operational risks
Our team builds a practical, phased plan based on system health and business goals. The process starts with stabilization and continues with careful upgrades that reduce complexity while business operations stay uninterrupted.

We focus on modernization for companies unable to grow due to aging systems
We replace only what must be changed, protecting your investment and CTO’s credibility.
HIPAA, HL7/FHIR, SOC2, GDPR, ISO compliance is integrated into every stage.
Integrating into your Git, CI/CD, and workflow tools, we make modernization visible, testable, and traceable
We uncover hidden costs, feature delays, and security gaps and offer ways of their removal
By providing CEOs stakeholder-ready roadmaps and progress metrics, we enable well-grounded transformation
They fulfill your task without seeking to address the issue at the root
Dispersing the focus, they fail to meet specific Healthcare G and other industry requirements
Generalized practices, regardless of the product, team, or business specifics
Initiate full rewrites instead of using the working parts and considering business context
Insufficient collaboration leads to poor handover, with documentation debt and weak enablement.
Development happens in isolation, prioritizing code delivery over actual business value.
If the software still fulfills business needs and brings value, it can be reasonable to continue using it. Competent legacy software support includes system stabilization, risk reduction, and restoring delivery confidence. This way, businesses can efficiently extend the life of their software without a complete overhaul.
Corsac Technologies is one of the top companies providing not only comprehensive modernization services but also continual customer support after the project is finished. Corsac’s team carefully transfers the required knowledge and trains your team. Professional engineers refine the modernized platform and ensure it performs at its best.
Legacy system support starts with software analysis and bug fixing. This step allows for addressing risks and issues at their roots. Then, engineers refactor and optimize legacy code for faster onboarding and safer evolution. They also enable smooth integrations, upgrade security and compliance, and conduct continuous monitoring of system performance. All these steps empower smooth, gradual modernization.
The maintainability of your system degrades slowly, without producing obvious signs of failure. It leads to system fragility and risky upgrades. You need appropriate support when modernization poses high risks, the system cannot be replaced right now, or your business prioritizes predictability over transformation. Corsac support systems that cannot fail yet must wait to be modernized.
By supporting legacy software, businesses can often retain key business logic and keep using the system that is already familiar to the staff. You don’t need to conduct a complete rebuilding with potential risks and disruptions. Moreover, teams don’t have to be extensively retrained to use new software. At the same time, your platform works smoothly, reliably, and safely.
