With a pacing, agile, and ever-changing market, only businesses that are capable of adapting to such environments can thrive and achieve greatness. And this adaptability can only come through the right kind of Digital Transformation strategies. Digital transformation not only automates the workflow and lets things happen faster but also provides a better customer experience allowing the scope of data-driven decision-making to serve the organization better. The only way to fully understand and enjoy the advantages of digital transformation is through Business and IT teams that are aligned properly while working in a synced collaboration.

But guess what? There are still a lot of businesses that are clinging to the old and outdated legacy systems like ERPs, CRMs, Hardware, and even the old operating systems. Using such legacy systems as the primary method to managing the flow of information is a pretty massive obstacle towards digital transformation and the agility and pace that come with it.

Legacy systems are rigid as they do not interact much with the current systems and can be difficult to navigate. But they are still being used which is maybe because of a rigid perspective and a misplaced satisfaction with the existing system or irrational fear of change.

So if you think that the legacy systems aren’t actually that bad, we are here to tell you the 6 very specific drawbacks that these legacy systems have (and, of course, the solution to fix it all so that your business can take advantage of a complete Digital transformation!)

Disadvantages of Legacy System

6 Drawbacks of Legacy Systems

1. Inaccessible data (no real-time data analysis!!)

Legacy systems force companies to have multiple disconnected systems to actually meet the needs of various departments. Such systems create a patchwork of different systems with almost zero data flow. A specific department does not have access to the data of other departments, which often is something crucial for getting things done. For example, if your company has different software for CRM and Invoicing, which are not integrated, then both systems will have different sets of customer data. These two sets of data need to be in sync with each other for effective management of customer data. However, issues arise when the data doesn’t match because of something minor, like a difference in how the customer has been named in the system, and it leads to duplication of the data for the same customer.

The constant copying and sharing of data from one system to another just so that all the departments have the necessary access to them may also lead to a lot of data loss.

To maintain the gaps in this patchy web of systems, teams work incessantly, spending a lot of their time and effort. As there is a delay in configuration and updation, it ultimately leads to delayed data analysis or, worse, no data analysis at all. Such conditions make it impossible for business leaders to get real-time data analysis that is needed to guide decision-making.

2. Legacy system complexities

As legacy systems produce a highly fragmented network of systems, the whole thing raises complexities. The working of the system becomes more and more complex as the patching work that goes into simulating an integrated system is often undocumented. Thus when a new issue arises in the system, it becomes a tedious task to actually find it in the already complex system.

Legacy systems also make it pretty difficult for new technologies like AI, ML, IoT, or even SaaS to be incorporated into the system as Legacy systems are old and cannot interact with new technologies, thus being a major obstacle for IT-Modernization. Such complexities make the overall organization slow and outdated, while the competitors might have an upper hand because of using the latest technological tools.

3. Maintenance and expenses

Legacy System software often operates in legacy system hardware as they often aren’t compatible with the new technologies. These very old designs of hardware take a lot of budgets to be maintained and thus can cost a fortune to the business. For example, very old and outdated operating systems can function well in old desktop systems. But when these ancient desktops need maintenance, some parts may not even be available in the market anymore which forces the business leaders to make special provisions to arrange those essentials by investing more time, effort, and even money.

The legacy system software is also coded in outdated languages like COBOL, and the framework maintenance requires someone with extensive knowledge of the specific language. Now the problem that arises here is that coders who know such outdated languages are very rarely found and may or may not be available all the time to fix small and big issues.

Legacy systems eat up a massive part of the IT budget for maintenance and fixing, which is why the IT team cannot provide the right tools and support that are essential for the organization to grow.


4. Less flexibility and agility

Legacy systems are pretty rigid in many ways. Not only they are incapable of interacting much with other systems, but they are also incompatible with a majority of new technologies. Even fixing minor problems in the systems is a big task as it requires the person to actually have a technical background and some experience of working with the particular system. It becomes impossible for an average business user to work their way through the legacy system and make the necessary changes for their work. This not only causes the IT team to have an extra workload but also creates a huge gap between the IT and the business teams.

The lack of incorporation of the latest technologies also cost the companies their agility, making them a pretty slow business with a stark inability to adapt in the fast-paced, changing market.

5. Cyber security issues

Legacy Systems may seem very reliable to the people who have been working with them for a long time. However, with the passing of time and the advancement of technology, there is another that has advanced significantly; Cybercrimes. According to Global News Wire, Cybercrime costs for companies will grow by 15 percent percent over the next 5 years, reaching $10.5 trillion USD annually by 2025, up from $3 trillion USD in 2015.

Because of being coded in outdated languages fixing the security loopholes in Legacy systems is a tough job due to the unavailability of coders. Thus the system is completely exposed and practically asked to be breached.

Along with the cyber security attacks, legacy systems also largely depend on hardware to keep data rather than having cloud-based storage. Security issues are a concern when these hardware malfunctions and important data is lost forever.

6. Innovative slowdown

World Economic Forum/ WE forum explains that innovation only comes when an ‘ecosystem’ of internal and external stakeholders is built by letting the data flow in both directions. In simpler language, customers’ experiences and issues are very crucial input for companies to come up with new and innovative product or service ideas. This cycle of problems, innovations, and solutions helps businesses grow, while the uniqueness of the innovations makes the company stand out in the market from the competitors.

However, legacy systems aren’t as flexible as they need to be to make such ecosystems and rather build a more ‘closed’ system where there is not much scope for an Omni-directional flow of data. Such systems make it pretty difficult to get insights into customer behavior, thus slowing down the process of innovation.

Legacy systems aren’t just annoying because of their rigidity but they can actually cost a lot of time and money to your business, be it through security breaches, hardware failures, maintenance, and fixing costs. So, how do we really deal with these ancient systems that have been exiting for so long and actually pave the way for digital transformation? The easiest way is to turn to no-code and low-code platforms! Even if you are still not ready to take the leap towards a complete transformation and believe that digital modernization will be more appropriate for your business, it is best to eradicate the obsolete applications of the legacy systems as they do not really serve anymore and enhance the systems that are still dependable with new systems build by no code/low code tools.

Eradicating or at least depending less on outdated legacy systems will not only pave the way for better performance and higher security but will also help your business become more agile. Th digital transformation will bring opportunities for growth as the decision-makers will have the advantage of making real-time data-based business decisions.
