The Importance of Legacy Modernization

Updated on October 28, 2014

There is no end to the demands made on modern IT teams no matter what industry their company is in. Amongst these demands, the common thread is usually that management wants to increase innovation while reducing costs. Obviously, this is no easy goal to meet. However, if there’s one solution that has a shot at helping you make a real difference where software performance is concerned while cutting costs at the same time, legacy modernization is it.

The methods one can use to achieve legacy modernization are as numerous as there are forms of legacy applications to address. However, the most ideal versions tend to have certain characteristics in common.

First, they begin with the most recent advances in software and platform innovations. Obviously, you don’t want to risk either going backwards with our applications or using an “advancement” that’s about to be considered obsolete.

That being said, usually you want to stay away from legacy modernization that completely dumps the old way of doing things on the scrap heap. For one, this method generally costs a lot of money. It can also cost you in other ways if you end up throwing out important information or methodologies along with the now irrelevant software.

So, secondly, you should try everything possible to leverage the prior investments your company made in business processes that have contributed to your bottom line in the past. Although they have become legacy applications, they may still be of some use.

Third, before your company begins down the road of legacy modernization, every step should be mapped out specifically. Nothing good will come from making any irrational decisions. This means knowing what you want the final product to entail and how your company will function along the way while you address your current legacy application. Considering that legacy modernization can often take years, you better have a reliable plan for the meantime and one that’s outfitted with a number of safety nets.

Even though it can come with a number of disadvantages, you should also be aware that sometimes it really is best if modernization means completely doing away with your prior applications. Sometimes updating it to a more modern version is completely realistic, but the timeline means your company wouldn’t last. Nonetheless, the third step still applies as you need to take every precaution to handle application modernization implementation flawlessly.

While there are a number of ways to go about it, legacy modernization is an essential part of any company’s development in the digital age. Get comfortable with this idea and look for ways to practice it when necessary.
