2. Understanding Legacy Systems:

Many great organizations have legacy systems at their core and navigating legacy systems can be a complex challenge. They have pieces of software, applications and IT solutions that are still widely used and fundamental to the overall running of the enterprise, but which are outdated and, in some cases, no longer even supported by the original vendor or software developer.

Legacy systems require modernization. Otherwise, they can be exposed to crashes anytime. That’s what happened on Tax Day 2018. Facing technical problems, the Internal Revenue Service couldn’t process electronically-filed tax returns. Although the IRS did not specify what went wrong, the fact that many of their IT systems were outdated at that time – two of them being nearly six decades old – might have contributed to the computer glitch.

However, a legacy system is not always defined by its age. It might be due to the lack of support or its inability to meet the needs of a business or organization that a system is considered to be legacy.

3. Risks and Challenges:

Legacy systems are technology, processes, or software applications that are outdated and can pose various risks and challenges to an organization. These risks may include security vulnerabilities, inefficient operations, increased maintenance costs, integration challenges, compliance risks, compatibility issues, and poor performance, among others. 

Addressing and mitigating these challenges is crucial to avoid impeding organizational efficiency and growth. In the following paragraphs, we will discuss each of these challenges in more detail, along with examples to help illustrate each point.

1. Security Risks

Legacy systems are more susceptible to security vulnerabilities and attacks because they were not designed to handle modern security threats. They lack the necessary security features and updates to protect against cyber-attacks.

2. Inefficient Operations

Legacy systems often lack the necessary features and capabilities to keep up with modern business demands. They can slow down business operations, resulting in decreased productivity and increased costs.

3. Increased Maintenance Costs

As legacy systems become older, they become more expensive to maintain. Hardware and software components become harder to find, and IT staff with the skills and knowledge to maintain the systems become more scarce.

4. Integration Issues

Legacy systems are often isolated from other systems and applications used by an organization. Integrating them with other systems can be challenging, requiring custom coding and significant resources.

5. Compliance Risks

Legacy systems may not be compliant with modern data protection and privacy regulations, such as GDPR and CCPA. This can result in hefty fines and legal penalties for an organization.

Organizations face a two-fold impact from legacy systems. Although these systems may have been useful in the past, they can create risks and challenges that can impede the organization's progress and achievements.


4. Benefits of Modernization:

If your company is using a legacy system, you’ll want to know what advantages you could gain from modernizing it. Here are just a small selection of the possible benefits:

Improved efficiency

If you continue using a legacy system, you may find that outdated hardware or software prevents you from adopting new technology and tools that are designed to work with cloud-based systems.

Modernization will allow you to access these tools and reap the benefits of improved functionality, productivity, and efficiency. You’ll also experience far less downtime (sometimes zero) as your provider will fix any technical issues.

Enhanced security

In the information age, data can be more valuable than gold dust to businesses and complying with the laws and regulations pertaining to its use is essential.

Luckily, migration to the cloud offers enhanced security for your data (though it should be noted that it’s your responsibility to configure services to meet your needs). Data stored in the cloud is more secure due to higher levels of encryption and less access by human staff to the data warehouses.

Remember to take steps to protect your data during the migration process, as this is often when it’s most vulnerable. This is especially important during insurance legacy system transformation for example, where the data in question can be extremely sensitive. 

Scalability and flexibility

Older legacy system hardware and software often have limitations that can be a barrier to scaling up a business. For example, growth might only be possible with  extra investment in infrastructure.

Following modernization, however, you will have the scalability and flexibility to easily grow your business (or even scale down when needed). This is because you won’t be limited by physical hardware. Therefore, your computing system can be tailored to ever-evolving requirements and changing business demands.

Reduced costs

Legacy systems often involve a lot of costs, from ongoing maintenance to investment in new hardware and software.

If you modernize, you remove these costs and only pay for the services and resources you’re actually using.

With monolithic architecture costs rising annually, modernizing means you should see significant savings year after year.

An improved user experience

You want your customers to be happy, and that means providing them with the best possible user experience. With a legacy system, there are limits to how you can improve this, but with modernization, the sky’s the limit. You can better store and protect customer data and develop applications and tools to make their journey smoother and more enjoyable.
