Software doesn’t appreciate in value, or get better with age like a family heirloom. But that’s not to say that your ageing systems don’t play a crucial in the smooth running of your business. So the saying, "out with the old, in with the new”, might be a bit overzealous. Legacy software modernisation can make the best of the systems that you already have without the need for complete redevelopment, keeping things ticking over while solving problems related to performance, flexibility and user experience.
Despite its many benefits, legacy modernisation presents its own unique challenges. Recent research by Advanced found that 74% of organisations that instigated the software modernisation process failed to complete it. Here are some of the most common reasons why:
Software modernisation is a complicated, multi-layered, multi-step journey. So, here's a comprehensive checklist to go through, before you embark on it.
The evaluation process is an integral part of planning your modernisation roadmap. It will help you assess the current condition of your application and answer crucial questions including:
Introducing new technologies with a MVP helps you carry out an upgrade while protecting the elements that matter most to your business and users. It filters product functions according to your needs. MVP strategy prevents you from overloading on new features and enables you to upgrade your apps in a more streamlined way.
This methodology facilitates software modernisation by stimulating presentations, processes, and screens, to check their value and validity. The MVP approach is used for upgrade approval and application testing before businesses kick-off the actual modernisation and global deployment.
Rigorous application evaluation can point you in the direction of the best modernisation approach to suit the needs of your business, helping you achieve the results you want more quickly.
Application re-engineering approach — this can be applied to applications which lack performance, security and other non-functional requirements, or need a complete conversion. The re-engineering approach can be implemented using a re-architect option or component replacement.
The application reconstruction approach enables you to introduce new technologies, platforms and systems, which match your business objectives and needs. Moreover, CRM, SCM and ERP can also be used as a replacement for a segment. Re-engineering of a legacy system creates a high-quality application with an optimised interface and better usability, performance, architecture, and innovative technologies.
Application migration approach — the aim of this approach is to fix minor flaws with news processes, code, or applications. Application migration varies from porting legacy software or web support to upgrading to a new version or platform. This may include re-hosting, re-factoring, or re-designing to improve performance or UX updates which don’t affect the business logic of legacy applications.
The migration of critical business data requires proper planning. This is one of the most essential steps to take before application re-engineering and migration, since it helps prevent unwanted data leakage.
You can add additional functions to it using modules or third-party integrations, however, don’t try to upgrade everything at once. Undertaking a systematic step-by-step process when modernising your applications is less painful and won’t compromise your other business processes. Furthermore, it will provide your end-user with enjoyable application training, and effective learning builds success.
Automated solutions are game-changing, making legacy application upgrades economically and technically feasible. Manually modifying an entire application — which might include numerous lines of code and multiple systems — can be inaccurate and sluggish.
Automated solutions won’t make your business fully automatic; they're applicable only to specific scenarios and play a particular role in modernisation. Application evaluation, data migration, and deployment, for example, can be automated using tools currently available in the market.
There are a plethora of reasons to upgrade and make the most of your legacy applications, and many elements to consider before you do. Among them:
