Legacy Software Modernisation Approaches

When modernising a legacy system, you update and optimise a business system so that it:
● Meets new customer expectations
● Addresses changing technology constraints or goals
● Boosts operational efficiency
● Supports integration with other systems
In other words, modernising legacy systems is important for enterprises that want to remain on the cutting edge of their industry, as well as continue to leverage new technologies for greater success.
However, anyone with experience will tell you that modernising a legacy system clumsily can result in severe setbacks or a waste of both time and money. For example, attempting to build a secure portal for your company’s applications when implementing an effective third-party option like 2GoTM will work just as well, would be a big mistake.
Let’s examine some smart legacy system modernisation approaches you can leverage for your business starting today.

Rehost the System for Accessing Remote Systems Securely

If your legacy system does not need to be drastically changed to work well with new apps, customers, or business needs, you may be able to simply redeploy your app to new infrastructure without making any underlying code modifications or changing its basic functions. This is sometimes referred to as the “container” approach where your legacy applications runs within a “container” to provide functionality within a new environment with minimal change.
Note that this approach only works with legacy systems that are already well adapted to your new business environment or objectives.

Evolve the System for Legacy Software Mobile Access

You may also evolve your legacy system more directly, such as by migrating it to a new runtime platform or restructuring existing code to better suit current business goals and functions.

An evolutionary modification approach is good for risk-averse executives who don’t want to upset things too much by completely replacing an existing system with new tech or apps. Furthermore, an evolutionary approach allows you to modernise one workload or part of your system at a time instead of forcing drastic change across your company all at once.

This approach however does not suit all businesses as there is often a significant amount of user re-training involved to make this approach successful.

Legacy Software Mobile Integration

System integration requires you to manually integrate a legacy system with new code, apps, or platforms. This approach is only possible if the code base for your legacy system and a new app or system are compatible.

If this is the case, your legacy system may be easier to modernise as opposed to tearing it down and rewriting it from the ground up.

Rebuild the System to an Enterprise “Cloud Ready” App

Of course, rebuilding your application or system from scratch is a possibility as well. This takes significantly more time and resources compared to more measured or evolutionary modernisation approaches, but it does allow you to address any integration problems or compatibility constraints that may exist with your legacy system and your new system.

Rebuilding your legacy system allows you to maintain its specifications and other factors, which may be a worthwhile benefit, depending on your needs but you should be prepared for significant finance and time investment to complete this modernisation.

Enhance the System with Enterprise Mobile Access Software

Lastly, you can choose not to replace your legacy system at all but use an external means of delivering it onto the latest devices. This is particularly relevant if you wish to avoid the costs and delay involved in the earlier steps and your users are resistant to the need to re-learn how to use what they already know how to use. However, this approach can deliver the benefits of modernization more rapidly and at least cost and it’s easy to integrate into your existing architecture.

For instance, 2GoTM Universal Mobile Access  is an effective and secure mobile application mobilisation solution. As a dedicated mobile use platform, it allows organisations to provide full and rapid access to all corporate applications on mobile devices without compromising digital security.

It’s also easy to use for existing employees, too, since all corporate applications can be accessed through a single, intuitive portal. Modernising legacy applications to enable mobile use has never been easier.

Ultimately, the right legacy system modernisation approach for your organisation will depend on your resources, time frame, and current workload. Consider all these factors carefully when making your decision, and don’t hesitate to check out 2GoTM Mobile Now if your business needs secure access to corporate applications through mobile devices.
