Legacy modernisation is the process of updating your old and outdated systems to better benefit your business. Whether you’re struggling with siloed systems which cannot connect or you’re suffering from not being able to scale your systems alongside your business, ensuring you’re updating your outdated systems is essential. 

Here at Jumar, we are experts in updating your legacy systems to ensure you’re complying with regulations, keeping your data safe, and scaling your systems to benefit any size of business – with a focus on flexibility and cross-platform collaboration. 

While the terms “old system” and “legacy system” are often interchangeable, and do often relate to similar systems, they do have some slight differences. An old system can simply be an outdated piece of software which, while it does perform a role, might not be the most efficient for your business. 

A legacy system, on the other hand, suggests a level of complexity and problem-solving needed to bring your business processes and software to the right standard. Often legacy systems can be old pieces of software or technology that could lead to issues with compliance, security, and compatibility with newer software models.

Any software or application which isn’t working efficiently for your business can be considered a legacy system. Some examples of legacy systems include: 

  • Legacy data and financial systems 
  • Outdated operating systems
  • Custom-built software that doesn’t have regular maintenance.

There are four types of legacy software which could be posing individual issues for your company. These include:

  • End-of-life software – this is software that is no longer supported by the vendor. This is typically the case when a new version of the old system is created separately from updating the system. This means your systems and software will no longer receive updates or bug fixes.
  • Limited scalability – these applications and software cannot grow with your business. While this software might have worked for your business previously, and will still work for others, your business can simply outgrow your software. If your software is struggling to meet the needs of your business, then the software could be considered a legacy system.
  • Outdated systems – if a new system is adopted within your industry, finding people who understand and can manage your older systems can be difficult. This can lead to the quick deterioration of your software, making it a legacy piece of software as the skills needed to understand the application diminish. 
  • Too many software updates - extensive updates can also lead to your technology becoming legacy software. This is because consistent updates can leave your systems vulnerable to cybersecurity risks.

Legacy software can often be unstable and unreliable, as they don’t benefit from the updates and fixes those modern systems and software have. They can also cause integration issues when you implement new software, as they often cannot work with the newer technology. 

This is why we provide bespoke application modernisation which works to integrate your systems and bring software up-to-date to optimise both your user experience and productivity. 

Replacing legacy software can come with many complexities including ensuring new and updated applications and software work alongside your current technologies. When it comes to replacing legacy systems, you will need to consider rebuilding, replacing, re-platforming, rehosting, and more. 

At Jumar, we have the expertise to replace the most complicated legacy systems, focusing on the safety, security, and efficiency of your technology.
