In plain words

What is legacy modernization?

Legacy modernization means upgrading old software so it is faster, safer and easier to change, without losing the data and workflows your business depends on. It can mean rebuilding slow parts, connecting the system to newer tools through APIs (ways for software to talk to each other), or moving it to the cloud.
