Let us learn about how to turn legacy IT systems into digital assets.

Every company wants to be agile and responsive even more so with the digital transformation driven by the COVID-19 pandemic. While cloud computing was the key technology for this journey, there were those who faced — or faces — another challenge: legacy IT systems.

While organizations want to get used to business dynamics to generate revenue, they need a good plan to update legacy applications. But how can this be done when you’re in the early stages of modernization?

A survey showed that 26% of companies interviewed are at this stage, taking their first steps to modernize IT. Already 19% said they have made enough progress on this journey.

But why is this “update” of IT necessary?

Modernizing IT is seen as serious for several reasons. Between them:

  • To provide better quality and faster software.
  • To run IT solutions with greater control and insights.
  • To integrate more security into the ecosystem.
  • To more quickly meet market needs.

Check out some tips on what it takes to upgrade legacy IT systems. Check out.

1. Know what legacy IT systems you have

Does your IT team have a good inventory of every running technology and what business processes in your company do they support? Having all of these mapped out is essential in building an effective modernization policy.

You might think this is obvious, but the reality is that IT managers don’t have a complete picture of all legacy IT systems and the functions they perform in the day-to-day running of an organization.

“Without that, you’re going to pay a big sum of money and have not much to show for ultimately.

Chances are that the executive doesn’t fully understand the processes these applications perform. The reason is that this C-Level doesn’t always know what the “data flow from start to finish” is like.

Invest in business complexity analysis tools. Thus, the IT area will be able to realize how data moves throughout the organization, enabling the creation of a modernization strategy. That’s really the key. That’s what decreases the failure risk.

2. Prefer projects according to business value

You have identified some systems that need an update. So wherefrom to start?

IT modernization is the same as boiling an ocean. You don’t know what’s inside, but whatever you’re seeking is there and we’re going to treat it until it’s found. On the other hand, business modernization is the same as boiling water in tea cup.

Therefore, modernizing infrastructure or applications should be based on your company’s business strategy. In other words, what must be modernized is what will bring tangible gains.

Systems must be seen as products

Modernizing legacy IT systems cannot be seen as a start-and-finish initiative. In fact, it is necessary to face it as a product, in which there is always the possibility of continuous improvement.


After all, technology has evolved at a very fast speed. So, probably an application that was developed yesterday will need to be improved tomorrow.

Knowing all this, call us for professional legacy application modernization services.
