Interestingly, organisations still use legacy systems to run their day-to-day business operations. As a matter of fact, most companies are dependent on legacy systems to power their customer-facing applications. These are the key findings of a recent study done by renowned institutions. Even though some organisations want to retire and decommission their old systems, shutting them down completely without a proper process in place can be risky for the business.
Among these many legacy systems, some systems are needed in the future for compliance purposes, for which your audit logs need to be maintained. This creates many challenges, and businesses may lack the resources or experience to undertake this work. Aside from this problem, what exactly makes organisations stick to their outdated systems? It's the project complexities, lack of proper planning, effective timelines, and, last but not least, relevant expertise that holds them back. You will understand more about this in the next sections of this article. Continue reading to know more about SAP decommissioning.
Understanding the legacy systems: An overview
If you have to define a legacy system, it is an outdated system, software or hardware that has served its purpose but is still in use. In fact, some of them are ancient news! Interestingly, an established institution conducted a survey that found that some companies are still using IT systems that were developed over 3 decades ago.
The technologies you use, your applications, and your software systems can turn into legacy systems for multiple reasons. These reasons include the fact that they no longer receive any updates, which is critical for system security. They are no longer available to buy or use outdated technology. All such limitations can turn into a security threat for a business. That's why letting go of such legacy systems with the help of legacy system decommissioning is the right way to go.
What is the main challenge behind keeping legacy systems?
Oftentimes, organisations consider keeping legacy systems because they think that it may cost a lot of money to decommission and replace them. Furthermore, instead of opting for the right option, they think, "Why not continue with the existing system and pay some extra maintenance costs?" But this is where the table turns 360 degrees, which often goes unnoticed!
The shortest answer to that question is: NO, maintaining a legacy system is not a viable option for the long term because it's difficult to evaluate how much is being wasted on maintenance costs. This is exactly the main challenge behind keeping legacy systems. In fact, many manufacturing and engineering organisations have admitted that they still use legacy systems, thinking that they may have to spend excessive financial resources on legacy system decommissioning. However, in reality, that's not the case.
The true costs of legacy systems
Organisations often spend immense amounts of money supporting, maintaining, and implementing legacy applications. Due to this, their budgets are increasing on legacy systems because of challenges related to routing management tasks, the need for technical support with specialised skills, and, in some instances, the need for special licensing. Companies can better utilise these financial resources once the legacy system is successfully decommissioned.
Are there any hidden costs of maintaining legacy systems?
Apart from the necessary costs of maintaining old codes, there are hidden costs that organisations may not see immediately, but they make a sizable dent in their pockets. These costs may include technical debt, which is the cost of not fixing problems in the systems that will affect them in the future. Moreover, they will end up paying more for unwanted software licenses and security, the environmental consequences of powering old systems, and lastly, the costs of missed business opportunities. Additionally, the outdated systems that businesses use to support customer-facing applications may lead to a poor customer experience, which can negatively impact the business's reputation in the future.
Unlock the power of legacy system decommissioning
After considering all the repercussions of maintaining legacy systems, there's some good news. Even with all the concerns about the SAP decommissioning process, change is now inevitable. Many top leaders are now considering system decommissioning as a top business priority. This significant shift is happening because legacy systems are regarded as a security risk, a hindrance to business productivity, and problematic for application integration.
Apart from business agility, security, and integration issues, the cost of maintaining legacy systems is another major factor for this shift. In fact, after an in-depth analysis of cost related to maintaining legacy systems and system decommissioning, it is almost always found that the former is more expensive.
Conclusion
In this article, you have explored how sticking with your old system may prevent future growth and scalability. Moreover, it may affect you in some other ways, such as preventing you from using your resources to introduce new products and services, expanding to new geographies, or introducing new services to your customers on new platforms. By effectively completing the legacy system decommissioning process, businesses can enjoy various advantages, including enhanced security to tackle cyber threats.
Moreover, obsolete systems usually consume excess energy and demand more physical space as compared to their modern-day successors. Downsizing and moving the data in a legacy system will actively contribute to your sustainability initiatives. From a business productivity perspective, these systems can be difficult to maintain and inefficient for long-term commitments. That's why decommissioning legacy systems is the way forward to improve efficiency. However, for a successful decommissioning journey, it is highly advisable to reach out to an expert for a smooth and seamless transition.
