Why Should You Modernize Your Legacy Systems?

Legacy Application Modernization Services

When a company invests in expensive hardware and software systems, at times it is reluctant to replace them, even when enough time has gone by for those systems to become obsolete, because of the financial commitment that the company had made with that initial expenditure. Over time, these systems become known as legacy systems, because they still provide the functions they were designed to, but they cannot expand their functions because their technology is too old to interact with the latest systems. Let’s talk about some of the ins and outs of legacy application modernization services, and some of the benefits that Excelsoftsources.com can bring to your operation.

Why do some companies resist updating their legacy systems?

It is true that maintaining legacy systems becomes increasingly expensive as time goes by, but those costs usually remain lower than the cost of upgrading to an entirely new system, both in terms of money spent and staff resources.

Another reason has to do with inertia – people tend to fear change. Particularly in the case of companies that have older employees, the benefits of legacy application modernization services are perceived not to outweigh the difficulties of changing to a new system, which can cause resistance.

Finally, the existing legacy system may have been constructed using a programming language that is no longer in common vogue, which makes finding migration personnel difficult. The documentation about the legacy system may no longer be in the company’s files, and in those cases, it is the planning process that makes upgrading to a new system difficult. In either of these situations, Excelsoftsources.com has the programmers and the talent to work through those problems and smooth the way to an upgraded system.

Is upgrading a legacy system really necessary?

Let’s say that you have been driving the same minivan for over a decade now. It’s paid for, so you’re not making monthly payments, but the engine is original. You know how to do a lot of the basic maintenance yourself, and you love how the driver’s seat feels. You can do your basic commute and run errands in it, and while others are telling you it’s time to ditch the minivan (your kids are grown and out of the house, for one thing), you’re resistant.

This is when a lot of the most expensive maintenance comes. You have to replace the catalytic converter. The alternator goes out. The serpentine belt on the engine has to be replaced. Then the air conditioner is next. These are high-dollar items that easily cost you what you could have put as a down payment on your next car – and this example explains why legacy application modernization services could be a game-changer for your company.

Just like with your car, maintenance is expensive and ultimately a waste of time. Sure, you can replace the alternator, but the air conditioner will still be a problem soon. With a legacy system, ongoing maintenance can keep the system operating, but as time goes by, the costs go up – and the benefits of keeping the status quo are no longer worth that expenditure. Once the updates run out, and the system fails, your company won’t have any backups.

With many legacy systems, your data is confined to silos. In many of the older systems, integration with other systems was never a design consideration. In the case of larger companies, one team might decide to upgrade, while the rest of the company might not – or one team might decide to save money and stay with the legacy system. There will be difficulties in communication between the teams, and moving data back and forth will be a hassle. Working with Excelsoftsources.com can solve that problem for your company.

When data becomes more difficult to maneuver and share, then compliance becomes more of a problem. One example of a more recent compliance system is the GDPR, which mandates that companies know (and be able to prove) what data they have for customers, where that data is stored, and who has access to it. For systems that remain in siloes for their data, meeting compliance requirements becomes a more onerous process.

One final reason to take advantage of legacy application modernization services is that companies that do not move to upgrade suffer from weakened security over time. Legacy systems still have such security measures as passwords that have been hard-coded. This was an innovation when those systems were designed, but it has become a liability. Hackers have figured out ways around those systems, and they are now easier to penetrate than more modern systems. Using Excelsoftsources.com to update your legacy system can help alleviate these security concerns.

What should legacy application modernization include?

The most significant benefit of legacy application modernization services has to do with moving your data to a system that is not only secure but also easier to share with other teams within a company. If you consider the example of a locally owned bank that has thousands of customers’ accounts in a legacy system. Problems with security could lead to a data breach that would lead to sensitive information being lost – and possible theft of the customers’ money.

Excelsoftsources.com has facilitated successful data migration as part of legacy systems modernization for many clients in a variety of industries. When it comes to migration, there are five steps to consider:

· Pulling out the data. In legacy systems, data could be siloed or, even worse, duplicated, fragmented, or just incomplete. It could have been stored in multiple formats or data stores. So the first step is ensuring a safe extraction.

· Changing the data format. Using data mapping, the team changes the data so that it meets the requirements of the new system. Because of the lack of compatibility between the legacy system and the new system, this can be the most sensitive part of the process.

· Cleaning up the existing data. This step involves removing duplications, pulling out incomplete data, and removing data, not in a proper format. One common example is a legacy system that includes dashes in phone numbers, moving to a system that no longer permits dashes.

· Validating data before the system goes live. This involves importing a sample data set to test for errors and problems to see if unforeseen issues have arisen.

· Importing data into the next system. The last step involves uploading all of the data into the modern system for use. If your company relies on legacy systems, reach out to Excelsoftsources.com today to find out how we can bring you up to date – and keep your data safe.
