It is increasingly difficult to maintain legacy IT systems, with systems run on legacy hardware that is unreliable and expensive. System security may also be lacking. 6B’s legacy software modernisation company will implement modern best-practices and work to identify pain points to reinvent your legacy software system, no matter how complex or old it is.

It’s time to face up to your legacy software challenges.


We get it – legacy systems are hard work, and the thought of replacing them can seem like a daunting task in itself.


But they don’t need to be, and the potential danger of not replacing them certainly outweighs the cost of time and money.


Legacy applications aren’t just slowing your organisation down, but leaving your critical functions, sensitive data and operations wide open to security breaches and a tremendous amount of risk.


It’s time to take back control of your systems – and it’s probably simpler than you think.

Our legacy software approach

We understand how complex legacy software can become. Often developed over many years, legacy infrastructure may be undocumented, with deep system knowledge held by only a small number of long-standing team members.

Our multidisciplinary teams adopt agile approaches, working in close collaboration with your team to redevelop your software using modern best practices and the latest technology.

Our legacy software modernisation process starts with research into how your existing platforms are utilised, and where the opportunities are for improvements in the new system.

Following an in-depth research phase, our legacy software modernisation team work to design, develop and roll out your new system. Through incremental application replacement, we’ll minimise business disruption so that you can continually operate.

No matter how complex the system or circumstances may be, we’ll always work to simplify the process and take the strain away from your internal team.

Our migration options

Working with legacy software systems can be challenging, both commercially and culturally. Fast-paced teams want to work with the best modern tools and they want to see changes rolled out at speed.

We offer two options to accelerate legacy software modernisation – we can build a new system to replace your legacy software, or we can modernise subsets of functionality in your legacy system to enable it to communicate with new technology.

In most cases, data does need to be migrated to the new system. But, if more appropriate, we can develop a system where data is synchronised between systems, so that a side-by-side rollout can occur.

Database engineers and scientists at 6B can carry out complex data migration scenarios smoothly thanks to our extensive experience. No matter your legacy software modernisation requirements, we’ll drive positive change within your company, and ensure you’re backed by the best, modern and future-proofed technology.

Three key strategies for legacy system transformation

Legacy software can be dangerous for your business - that's why we've broken down the three key strategies for transforming your legacy applications.

How your legacy system is holding you back (and what to do about it)

We’re living in an era defined by innovation. The speed at which technology moves means that software that was cutting-edge a few years ago may now be obsolete.

How your outdated systems are holding you back

Non-value added time has always been a problem. What do we mean by it? Any action that doesn’t add benefit to a product or service – with said benefit or value being defined by the customer.
