Legacy system
Author : Binny Vyas   Posted :

Legacy systems are no longer capable of surviving the cutthroat competitive nature of today’s information technology (IT) infrastructure modernization. With the system modernization you demand today, you’re playing a new game with new rules. Especially if you choose to modernize not only the tools and functions, but also the way your organization uses IT.

IT activities must enable cutting-edge capabilities in areas like data analytics, cybersecurity, automated processing and integration with third-party systems. Organizations must remain focused on their competitive advantage and your infrastructure modernization initiatives must add value across the gamut.

DO’S

Do understand what’s driving modernization

Every organization must not only be skilled at modernization, but also understand what drives modernization. It is the requirement for flexibility and agility in order to integrate IT technologies capable of meeting your company’s needs. Let’s get one thing clear: legacy mainframe applications are frequently incompatible with today’s open-system platforms.

Organizations that rely on outdated technologies are generally limited in their ability to meet critical business demands and capitalize on future growth opportunities. It is also emphasized that the high cost of maintaining outdated applications and systems is driving infrastructure modernization.

Do evaluate your organization’s current-state technical landscape

When evaluating the current state of your technological infrastructure, you’ll need a solution that incorporates both technology and business process tools at each stage. As a result, it is advised that you begin with an evaluation that results in a complete mapping of your business as well as an explanation of your apps and architectures in order to develop the best modernization strategy. Several IT service providers like us offer a variety of deployment choices, ranging from a progressive rollout to a big-bang deployment.

Do design for flexibility and speed

As a modern company, you must constantly adapt to an ever-changing environment, which necessitates ongoing innovation in products, services and procedures. As a result, you’ll need to create a more flexible and adaptable architecture using modular technologies. These solutions can quickly handle a variety of connection and configuration options.

It is advisable to keep an eye out for modular platforms that can handle a wide range of plug-and-play functions for your business, including those that have yet to be built or imagined. Develop your skills in the design and deployment of advanced IT systems that can flex to accommodate innovation.

Do organize your IT infrastructure by capabilities

Most businesses are unable to completely rearrange their legacy IT systems at once. What if you grouped them according to their infrastructural capabilities instead? The most distinctive capabilities are the combinations of systems, processes and operations that provide your company with unique value. Consider the modernization of your system project as an opportunity to strengthen these capabilities proactively, leveraging your digital knowledge.

You don’t have to worry about the multiple layers of the technology stack when you organize by capabilities. They’re all covered. Your IT department is no longer constrained by traditional ideas; principles such as mobile access, API-based design, microservices, cloud-based infrastructure and modular IT structures can help accelerate the digital transformation.

Do work with a partner on shared values and trust

Your organization’s future depends on the technical systems you modernize today. As a result, don’t think of modernization or goods and services as a transaction. Working with a long-term partner who uses standard evaluation criteria is recommended. Look for organizations that can provide mutual benefits and with whom you can establish a working relationship based on mutual commitment and creative collaboration.

DON’TS

Do not rely on aging hardware

Legacy system modernization can be an endless journey that promises to boost corporate performance, optimize processes and provide new ways to serve customers. Several enterprises are likely to invest in reengineering processes and IT systems to realize their strategic vision. This can be an arduous journey to take, but it can be even more difficult for businesses whose crucial business processes rely on old technology and legacy software. These outdated systems are frequently incompatible with the technology platforms required for digital transformation with app modernization.

Do not use a legacy system to run a mainframe for core business operations

Mainframe applications remain the backbone of enterprise IT infrastructure, especially for businesses that rely on high-volume transaction processing. In fact, most major firms still rely on mainframe-based legacy apps for fundamental business operations. Although these systems are outdated, they have been fine-tuned over time to deliver necessary business functionality. Consequently, mainframes are expected to remain at the core of IT and hence, they should match innovation with the changing digital landscape. 

Do not opt to ‘rip and replace’ legacy systems with a new system built from scratch

There are several always to modernize IT and each company’s approach will be determined by its strategic priorities. Many companies choose to “rip and replace” legacy systems in favor of a brand-new system developed from the ground up. Others may opt to create a custom commercial solution or transfer technologies, processes and people from a third-party source.

These methods may have benefits, but they are often expensive, dangerous, time-consuming and disruptive to the organization. Organizations should instead choose fully automated migration, which uses technology to move legacy code and data to current platforms and allows them to modernize in stages without disrupting business operations. This could be a more effective option.

Do not choose to tailor a new off-the-shelf software solution

Many companies choose to customize a new commercial off-the-shelf software solution or to transfer technologies, processes and personnel from a third-party vendor. Although, in comparison to custom systems, which can take many years to demonstrate value, such a solution often gives a faster, more accurate alternative to traditional custom reengineering. However, it can be costly and time-consuming to do so. Moreover, it can also disrupt the current business operations and necessitate new system requirements. 
 

It’s time to begin your modernization journey

Application modernization is a process that takes time. It is always preferable to define the scope of your modernization landscape and use a low-risk approach that focuses on core system improvements rather than recreating what currently works.Get in touch with a solution provider like us to help you replace legacy systems with new systems by addressing the key areas that can be improved and leveraged across your projects.
