No matter how complex the system or circumstances may be, 6B makes legacy software migration easy for your organisation. Our service ensures no disruption to your organisation, your costs will be managed and 6B provides the necessary resources to modernise your legacy software, taking away the strain from your internal team..

6B team members

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

6B offers two options to accelerate legacy software modernisation – either building a new system to replace your legacy software, or we can modernise subsets of functionality in your legacy system to enable it to interface with new technology.

In most cases, data needs to be migrated to the new system. Alternatively, 6B 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, 6B will drive changes to your software and systems to ensure your organisation is running the best, modern and future-proofed technology.
