Update and Upgrade, Without Starting Over

Apr 11, 2017 | by Slava Koltovich

Let’s face it. Organizations struggle with their legacy applications. Even when they still solve some of the business’ problems, they reach a point where they can no longer keep up with market and industry demands.

Even when they were smartly designed and well-built, they were often implemented as monolithic systems. Eventually, applications created by different departments or obtained through M&A aren’t communicating with each other, and are often implemented using different technologies stacks.

They are hard to update and grow – each small change requires thorough full application retest. Pushing new functionality into production also requires a full redeployment, which has to be well planned in advance and usually requires some downtime. Considering disconnected nature of those apps, each new requirement has to be implemented in several apps, which substantially increases the level of effort and risk.

Operationally, it sounds like a headache. And, then there’s the cost considerations. So it’s understandable that you might decide it’s not worth the hassle. But don’t make that mistake.

Many organizations see a full rewrite as the only way to get rid of legacy systems, however those are risky and costly projects that not every organization can afford. On the other side, your business needs new functionalities today, not years from now when all the apps will be implemented from scratch.

We know this because in our experience, we’ve met these seemingly impossible challenges for our clients while saving them time and money. We utilized a different approach that allows modernizing legacy apps without rewriting them from scratch.

It’s not free, and it requires a significant level of effort – but it’s worth it.

In contrast to the “full rewrite” method, this distinctive approach uses the iterative improvements method – where every iteration immediately creates some measurable benefits. So, think of it as a rather large scale refactoring than a rewrite. And while this refactoring takes place, new functionality can be added to the applications. There are several key parts to this approach:

As I said, it requires some effort, but the ends justify the means. And, don't think you have to eliminate your legacy systems to increase efficiency and performance. However, don’t just jump into new stacks or apps without doing an internal/external discovery, or at the very least a feasibility study. With a little homework and less hassle than you expected, you can get your systems up to date without leaving their parts
