In today’s fast-paced digital world, staying ahead, or even up to par, in the technology game is increasingly a necessity for businesses. When a business considers a full overhaul of the majority of their legacy systems, it is typically referred to as legacy modernization. Legacy systems, often seen as the backbone of many enterprises, are increasingly becoming a sometimes seemingly insurmountable hurdle in the path of innovation and efficiency. This is especially true in sectors where rapid technological advancements are the norm.

Why should companies consider modernizing their legacy systems? The answer lies in both people and technology. New generations entering the workforce and customer bases have different expectations for the tools that help deliver or receive good service. Technology, especially with tools like generative AI, is in a position to help companies scale in ways that weren’t possible even five years ago. With newer expectations for and technologies that offer improved efficiency, security, and scalability, sticking to outdated systems can hold businesses back from achieving their full potential. Modernizing these systems is not just about keeping up with the times; it’s about unlocking new opportunities for growth and staying competitive in an ever-changing market.

Understanding Legacy Systems

In the realm of technology, legacy systems are like the old giants of the forest. They’ve been around for a long time, deeply rooted in the organizations that use them. But what exactly are these systems, and why do they become a challenge over time?

What is a Legacy System?

A legacy system is any software, hardware, or integrated system created in the past that is still in use today. These systems often form the foundation of many critical operations in businesses. 

Legacy systems were once cutting-edge solutions, perfectly suited to the needs of the time, but rapid technological evolutions can quickly render these once state-of-the-art systems outdated, less efficient, and more challenging to maintain. Moreover, they may not easily integrate with newer technologies, making them rigid in a world that demands flexibility and unsupportable for the organizations who rely on them for daily operations.

Challenges Posed by Legacy Systems

The primary challenges of legacy systems are their age and architecture. Legacy systems often require specialized or even tribal knowledge to maintain, which can be hard to find as newer technologies emerge. 

Security is another major concern. Older systems weren’t designed to combat today’s sophisticated cyber threats, making them more vulnerable to attacks.

Legacy systems can also be expensive to operate and maintain, often needing custom support which adds to the cost. Often, depending on the age or version of the technology, there simply isn’t support. Furthermore, they may lack the agility to meet the changing demands of the business, hindering growth and innovation.

For many businesses, some kind of catastrophic failure looms. Years upon years of updates, lack of upgrades due to costs or disruption, complex architectures due to systems being added to the business over time, all become a house of cards that, at some point, will fall. External events like the recent pandemic or unforeseen issues caused by updates like the recent AT&T outage are examples of risks to legacy systems and the businesses they serve that would be alleviated with modernization.

Importance of Modernizing Legacy Systems

In a digital age where agility and innovation are key, modernizing legacy systems is not just a luxury—it’s a strategic move towards future-proofing businesses. Modernization is critical for companies aiming to stay competitive and responsive in the digital era and can transform the way businesses operate by:

Boosting Efficiency and Productivity

Legacy systems often struggle with the demands of modern business operations. Modernizing these systems offers significant improvements in processing speed and operational efficiency, enhancing overall productivity. Organizations that update older or mainframe systems experience faster processing, better resource management, seamless integration of business intelligence (BI) into core systems, and reduced operational and maintenance costs.

In terms of cost savings, large enterprises can spend as much as 80 percent of their IT budget on maintaining and operating legacy systems, which is both inefficient and not scalable. By identifying and modernizing applications critical to business, companies can allocate funds to growth or innovation instead of maintenance and support.

Meeting Current Market and Customer Needs

Modern markets are dynamic, with customer preferences and industry standards constantly evolving. Legacy systems, built for a different era, can hamper a business’s ability to adapt to these changes. 

Modernized systems, on the other hand, are designed with flexibility in mind, allowing companies to quickly respond to new market trends and customer demands, ensuring they remain relevant and competitive. Modernizing these systems is also crucial to providing customers with a refined interface and cutting-edge features, which will ultimately improve customer satisfaction and loyalty​​.

Adapting to New Generations Entering the Workforce

Legacy systems typically require significant investments in time and training for new personnel due to complex, layered architecture, brittle code, lack of monitoring, and tribal knowledge required to fully support them. 

With client expectations for modern, clean interfaces, and high customer service so comes the demands of new generations entering the workforce whose skill sets and training are focused on newer technologies.

Ensuring Security and Compliance

One of the greatest concerns with legacy systems is their vulnerability to security risks. As cyber threats become more sophisticated, outdated systems become easy targets. Modernizing legacy systems not only strengthens security measures but also ensures compliance with the latest regulatory standards, protecting both the company and its customers. 

The average cost of a data breach was estimated by IBM at $4.35 million in 2023, the highest on record. With legacy systems in place, the time and expense to identify and contain a breach can often be measured in weeks or months. Monitoring and instrumentation help with this, but their abilities are either limited or prove to be cost prohibitive when implemented with older technologies.

Modernization addresses these security concerns by integrating advanced security measures like role-based access control (RBAC) and multi-factor authentication. Additionally, it helps implement best practices around fraud prevention, thereby safeguarding vital assets and ensuring compliance with current security standards​​.

Common Modernization Approaches

Modernizing legacy systems can be achieved through various strategies. Here are some of the most common approaches:

• Rehosting (Lift and Shift). By moving applications to a new physical, virtual, or cloud infrastructure without modifying the code, rehosting is a quick and cost-effective way to gain some benefits from modern infrastructure.
• Replatforming. Replatforming makes minimal changes to the code to adapt to a new platform and optimizes the application to leverage new features.
• Refactoring/Redeveloping. A more comprehensive approach involving significant changes to the application’s code, refactoring or redeveloping leverages modern capabilities, like cloud-native features.
• Retiring. In some cases, the best approach might be to simply retire an application that’s no longer needed or cost-effective to maintain.
• Retaining (and Encapsulating). Retaining involves keeping the legacy system but encapsulating its functions in a new interface, allowing for more modern user interactions and integrations.

Each approach has advantages and challenges, and the right choice for your legacy system depends on factors such as your business’s specific needs, budget constraints, and long-term strategic goals.

In most cases a progressive and iterative approach to modernization that deploys a combination of these strategies applied to the right technologies is the most cost effective, agile, and least disruptive to the business leaving the organization with a modern, scalable, and durable technological foundation for the coming decades. 

Factors to Consider When Choosing a Modernization Approach

Selecting the right modernization approach is a balancing act that requires careful consideration of various factors. By aligning the modernization strategy with the organization’s unique needs and limitations, businesses can ensure a smoother transition to modern systems and reap the benefits of enhanced performance, scalability, and security.

Several key factors must be considered when choosing the right strategy for modernizing legacy systems, such as:

• Business objectives. It’s important to understand the goals your organization is trying to achieve through modernization. Are you looking to improve efficiency, reduce cost, enhance the customer experience, or all of the above?
• Budget and resource constraints. Not all modernization methods require the same level of investment or expertise, so your chosen approach should align with your available resources.
• System complexity and interdependencies. The intricate nature of the legacy system and how it interacts with other systems plays a significant role in determining the feasibility of different modernization strategies.
• Future scalability and adaptability needs. Long-term success of your modernized system is heavily dependent on its ability to grow and evolve with your business.
• Risk assessment. Identifying potential problems that could arise during the modernization process can help make sure you choose an approach that minimizes disruptions and risks.

The Role of Custom Software in Legacy Modernization

When modernizing legacy systems, “build vs buy” is always a question. Often, the answer is both–the magic happens when these approaches are optimally combined. There are capabilities that can be purchased that are not practical to build from scratch and others that would take so much configuration that by the time the implementation was finished, it would have been more cost effective and produced a better solution to build. The key to the strategy is working with a trusted partner who can help navigate when and where and how to deploy each approach.  

Custom software offers solutions that tend to be more precisely aligned with a business’s unique requirements. Custom software can provide a host of capabilities that integrate with diverse platforms, maintain business continuity, and transform outdated legacy systems, creating maximum value through:

Tailored Solutions

Custom software offers the advantage of being built specifically to meet the unique needs and challenges of a business. This bespoke approach means the software can be crafted to align with a company’s specific processes, workflows, and objectives, ensuring that the modernization effort adds maximum value and efficiency.

Integration with Diverse Platforms

The ability to integrate seamlessly with a variety of platforms is a hallmark of custom software. This flexibility creates a cohesive ecosystem where new and existing systems work together harmoniously. Custom solutions can bridge gaps between disparate technologies, streamlining operations and data flow across the organization.

Maintaining Business Continuity

An essential aspect of legacy modernization is ensuring that business operations remain uninterrupted. A custom modernization strategy can be strategically developed and implemented to minimize downtime and disruption. This approach allows for a smoother transition, as custom solutions can be tailored to fit within existing infrastructure and processes or accommodate integrations with purchased capabilities, ensuring seamless integration and continuous business operations.
