Why it’s important to modernize a legacy system on time
Legacy systems are painful for their owners, as they slow down or even block business processes, increase the risks of security issues, and make it harder to keep up with the changing market dynamics. The on-time system modernization helps you avoid the following drawbacks in your work:
The expenses of legacy system maintenance and support are typically higher than the cost of its modernization. The maintenance costs of sophisticated, large-scale systems may reach up to $7 to $19 million dollars per year.
Legacy systems have more vulnerabilities that can be easily exploited by cyber attackers. According to the research, 60% of small companies shut down within six months of falling victim to a data breach or cyber attack.
Legacy systems are far less efficient than the modern ones and do not align with the current IT demands. Poor performance significantly slows down operation processes and reduces the employees’ productivity.
Business requirements are subject to constant changes; and legacy systems are unable to keep up with this pace. Investing in obsolete technologies makes your business lose against the competitors.
Legacy systems in use: reasons, challenges, use cases
Even when acknowledging the high maintenance costs and the need for modernization, many companies still hesitate to reengineer their legacy systems. Factors such as familiarity, fear of technology risks, and uncertainty about the modernization process often hold them back. Below are the key reasons behind this hesitation.
Legacy system features
- Built on obsolete tech
- Prone to security risks
- Expensive to operate
- Hard to customize and evolve
Why still in use?
- Security concerns
- Pressure to deliver service non-stop
- Fear of disruption
- Risk-averse culture
- No tech expertise to modernize

FAQ
By a legacy system, we mean the system based on decades-old, obsolete technologies that a company has to use to support their vital business processes, perform essential functions, and maintain daily operations. Typically, such systems are no longer supported and hold the companies back from business progress and scalability.
Legacy software is not just about outdated and unused systems. It reaches its legacy status when the costs and risks of upgrading to modern tech outweigh the benefits, justifying the decision to stick with it.
Legacy system modernization is a set of services aimed at upgrading an outdated or inefficient system to gain additional value for business. Typically, the modernization lifecycle includes a legacy system assessment, defining the modernization scope, executing the modernization process, implementing upgrades, testing, and providing ongoing support.
Legacy systems pose compliance, security, and integration problems that kick the companies out of the market competition. The on-time system modernization helps you avoid the following drawbacks in your work:
• High maintenance costs - The expenses of legacy system maintenance and support are typically higher than the cost of its modernization.
• Security threats - Legacy systems have more vulnerabilities that can be easily exploited by cyber attackers.
• Poor scalability and performance - Legacy systems are far less efficient than the modern ones and do not align with the current IT demands.
• Limited business opportunities - Business requirements are subject to constant changes; and legacy systems are unable to keep up with this pace.
The main legacy system assessment challenges include:
1. Understanding the existing codebase and architecture - When the developers and architects who originally designed the system are no longer available, it may be difficult to understand the reasoning behind certain design decisions and functions.
2. Outdated technologies and third-party libraries - It’s an indispensable attribute of any legacy system, which causes incompatibility with other solutions and harder migration to the modern platforms.
3. Lack of application knowledge within the organization - Typically, legacy systems are associated with poor documentation. Over the years, it can simply disappear or get obsolete.
4. Business logic embedded in the code - Changes that a company may need to introduce to its operation system can disrupt some business-critical processes. This happens when the business logic is deeply embedded in the code.
5. Identifying and mitigating risks - Modernizing a legacy system implies new digital capabilities and significant increase in its agility. This means that the business must be aware of the potential risks associated with outdated IT infrastructure and get prepared for large-scale changes accordingly.
If your legacy system has performance issues, is hard to maintain, impossible to integrate with other systems, and is ultimately incapable of meeting modern standards of security, then modernization might be worth considering. Regular audits and feedback received by your IT team will also be instrumental in assessing its current state. At TYMIQ, we also provide IT consulting and audit services if you need external expert assistance.
Actually, there are several proven modernization strategies designed to cater to specific business needs and challenges. The selection of a strategy depends on the business objectives, workflows, and constraints.
1. ‘Adapt’ strategies
- Replatforming (‘lift and reshape’): Migrating applications to a new platform with optimizations to prepare for a new environment.
- Rehosting ( ‘lift and shift’): Migration of the applications to another environment, without changing the codebase for minimal downtime The primary goal is to migrate quickly under tight deadlines and with minimal resources.
2. ‘Improve’ strategies
- Refactoring: Making code changes to improve structure, readability, and maintainability. Typically, refactoring is used to identify and eliminate idle features, streamlining maintenance.
- Rearchitecting: Changing the app's architecture to address scalability, performance, or other critical issues. It goes beyond refactoring, as you restructure the entire system to align with modern design principles.
3. ‘Transform’ strategies
- Rebuilding: Redesigning apps from scratch to leverage modern development tools and practices.
- Replacing: Introducing new software or custom-built solutions, to meet the business requirements with zero downtime.
The time frame for modernization is based on the complexity of the system and the strategy that you chose. It could be only a couple of months, or for bigger, more complex systems, perhaps several years. A pronounced staged implementation, by the way, usually paves for a smoother transition.
There may be interruptions during migration; however, proper planning and a phased approach can minimize downtime. Communication with stakeholders is very important to set up their expectations. At TYMIQ, we have implemented several projects where uninterrupted operation of a modernized system was a requirement, and our team kept it functional during migration.
Legacy system modernization may seem complex and requires excellent knowledge of the old system and new technologies. Bringing in the experts can greatly minimize risks and assure proper and efficient handling of the process. Many businesses are turning to third-party consultants or companies that specialize in legacy system modernization, like TYMIQ.
Although modernization carries high upfront costs in most cases, they are usually outweighed by savings in maintenance, security, and operational efficiency over time. Costs vary depending on the extent of modernization undertaken, the strategy chosen, and any new or additional hardware or software required.
Success can be evaluated through improved system performance, fewer outages, savings on operational costs, security enhancement, ability to scale, and integrate with current technologies. Monitoring KPIs before, during, and post-modernization will assist in assessing the attainment of objectives.
