How to Maintain Old Software

In today’s fast-paced technological world, it’s easy to get caught up in the latest software and hardware trends. However, there are still many companies and individuals who rely on old software that they have invested significant time and money into developing. While some may see this as a disadvantage, there are ways to maintain and even improve the functionality of old software.

Many organisations may look at their old software and wonder, what are the best practices for maintaining old software, and why it’s important to do so? We’ll also provide some tips for how to ensure your software stays up-to-date and relevant.

Why is Maintaining Old Software Important?

There are several reasons why maintaining old software is important. Firstly, old software can contain valuable data that may not be easily accessible with newer systems. For example, a company’s accounting software may contain years of financial data that is vital to its operations. If this software is not properly maintained, that data could be lost.

Secondly, old software may still be the most effective solution for certain tasks compared to other more modern “off-the-shelf solutions”. Some software may have been developed to suit a specific business process or industry, and the newer more generalised software may not offer the same level of customisation or functionality.

Finally, maintaining old software can also save a company significant money in the short term. Developing new software can be expensive and time-consuming, and if an existing system can be updated or improved, it may be a more cost-effective solution.

Best Practices for Maintaining Old Software

  1. Regular Maintenance and Updates

One of the most important things you can do to maintain old software is to perform regular maintenance and updates. This includes checking for bugs and security vulnerabilities, updating software dependencies and libraries, and ensuring that the software is compatible with newer hardware and operating systems.

Regular updates also help to ensure that the software stays up-to-date with changing industry standards and regulations. This can be particularly important for businesses that operate in heavily regulated industries, such as finance or healthcare. This is also important for businesses operating with large amounts of sensitive data, as data breaches can be costly to brand reputation and bring large fines, as in the case of both Optus and Medibank.

  1. Documentation

Another key practice for maintaining old software is to keep detailed documentation of the software’s code, architecture, and dependencies. This documentation can help developers understand how the software was designed and built, which can make it easier to identify potential issues and make updates. This can help to ensure that the software is maintained over the long term, even as team members come and go.

  1. Testing

Testing is another important practice for maintaining old software. This includes unit testing, integration testing, and regression testing. Unit testing involves testing individual components of the software, while integration testing involves testing how different components of the software work together. Regression testing involves testing the software to ensure that previously developed and tested software still performs as expected.

By regularly testing the software, issues can be caught early on and ensure that the software is running as intended.

  1. Legacy Code Refactoring

As software ages, it may become difficult to maintain or update due to outdated code or architecture. Legacy code refactoring involves re-writing or restructuring the software’s code in order to make it more maintainable and easier to update.

While legacy code refactoring can be a time-consuming process, it can also make it easier to maintain the software over the long term. It can also improve the software’s performance and reduce the risk of bugs or security vulnerabilities.

Tips for Maintaining Old Software

  1. Prioritise Security

One of the biggest risks of maintaining old software is the potential for security vulnerabilities. Older software may not have been designed with modern security threats in mind and may be vulnerable to attacks. It’s important to regularly assess and update the software’s security measures, along with the infrastructure the software is running on, ensuring data backups, access controls and updated operating systems.

  1. Plan for Future Updates

While it’s important to maintain old software, it’s also important to plan for future updates. This includes understanding the software’s lifecycle and planning for any necessary updates or migrations to new systems. This can help to ensure that the software remains relevant and functional over the long term.

  1. Consider Customisation

Old software may not have been designed to meet all your current business needs. Consider customising the software to suit your specific needs. This can involve adding new features and functionality or integrating the software with other systems.

  1. Don’t Delay Upgrades

While it’s important to maintain old software, it’s also important to know when it’s time to upgrade. Delaying upgrades for too long can lead to compatibility issues and security vulnerabilities. Keep an eye on the software’s lifecycle and plan for upgrades as necessary.
