Even well-performing legacy systems might ultimately become roadblocks to advancement. Therefore, it should come as no surprise that 92% of firms are engaged in application modernisation projects or have one planned. But dealing with the challenges of modernising ancient applications isn’t easy, particularly for big businesses and software providers. To carry out a job like this effectively, you have to know how to do it correctly. This is the point at which an effective application modernisation plan is useful.  

What is the Modernisation of Legacy Applications?

The process of updating an existing legacy application’s internal architecture, functionality, and platform infrastructure is called legacy application modernisation. Today’s modernisation is mostly applied to monolithic on-premise programs that are maintained via the usage of the waterfall development method. Along with release patterns like microservices and DevOps, it also takes into account how the applications are integrated into the cloud infrastructure.

Advantages of a Successful Application Modernisation Plan

Not only may modernising your applications help you stay abreast of technological advancements, but it also ensures real commercial advantages and development. A company like modlogix.com can help you implement your plan, and you will receive the following benefits:

1. Reduce operating expenses: Applications that are modernised tend to be more effective, need less maintenance, and make use of cloud-based solutions, all of which may reduce overall IT expenses.
2. Increased scalability and flexibility: Updated applications can expand to handle more work and react faster to changing company demands.
3. Enhance the user experience: Updated apps perform better and offer more functionalities, which is beneficial for users and employers.
4. Better security: Today, various technologies are installed with better security features that help in preventing the dangers that are present on the internet today.
5. Enable competitive advantage:  In the contemporary economy, it is often said that if you are not up to date with the latest technology, it may put you at a disadvantage.

Steps to Modernise Legacy Systems and Applications

Updating the old applications and systems is crucial for organisations that want to remain relevant in the contemporary world.

Evaluate Legacy Systems: The first of the six drivers that need to be considered when assessing legacy systems in the context of modernisation is the assessment of your current legacy systems. These drivers are on both the business and IT sides, such as business alignment, value, flexibility, cost, and risk. If your legacy application is failing to deliver in terms of meeting business needs, or offering value, or not being able to meet digital needs, then it is a clear signal that modernisation is required.

Define The Problems: After you have defined what drivers require modernisation, it is time to dig into the problem. Determine what hinders users from achieving their goals, whether those goals are to purchase a product or to effectively do a job. It is crucial to identify specific issues that may exist and, no less important, to identify those components of the legacy system that perform well. This understanding will help in defining your modernisation strategy.

Choose the Modernisation Approach: The type of modernisation approach to be chosen depends on the workload, architecture, cost of implementing and maintaining the new modernisation approach, risk involved, operations, and security issues. The decision may also depend on some factors within your company, competition and demands of the market.

Prepare for Future Growth and Changes: Traditional systems are mostly developed in a single large block which makes it difficult to incorporate new functionalities and features. Select a modernisation strategy that provides the capability to handle future changes in the organisation. For example, the software that has been refactored or re-architected can be more suitable for your organisation’s needs in the future.

Choose the Right Modernisation Partner: In most cases, your organisation may not have all the internal capabilities required to make sound decisions about modernisation, let alone if it is not your core business. Think about cooperation with skilled professionals in the field of digital transformation who can redesign the technology, systems, and processes using different approaches to modernisation. Search for a team that implements Agile and DevOps to help you complete your modernisation project faster and achieve the best time-to-market.

Observe and Optimise: It is also important to conduct regular testing and improvement of your modernisation project once you start it. Continuously evaluate the changes made to the application to determine the problems that may arise in hosting, license acquisition, and integration with other services, and databases, to ensure that the application meets the changing demands efficiently.

Final Thoughts On Modernising Legacy Applications

Gaining a better knowledge of the enterprise’s data environment is the primary objective of modernising outdated applications for both IT and business. Resilience is further ensured by modernising legacy applications. It is your goal to protect the newly launched cloud application from unintentional, disastrous modifications brought on by an error made by someone else in the company. We can conclude that modernising old applications brings the business and IT together by weighing the company’s requirements against the IT’s capacity to provide them.
