A brighter business future awaits

Every legacy system is different, but there is often one tier (often the data tier) that can be kept and evolved. From time to time more is possible depending on your needs and budget. At MercuryWorks, we’ll work with you through the discovery and assessment phases to minimize reinventing the wheel. If there are parts that are working well in your current application, they can definitely stay.

We incrementally migrate legacy systems one piece at a time using the enterprise Strangler Pattern.  We pilot the modernized incremental portion of the system, get feedback and ensure its stability.  We then strangle out the next module/feature and repeat the process.  As features from the legacy system are replaced, the new system eventually replaces all of the old system’s features and the legacy system shrinks in size until you decommission it.

First, we can rearchitect a monolithic legacy application into smaller, independent units called microservices, which carry out functions independently. This reduces time for maintenance and troubleshooting and makes adding features easier moving forward. Second, legacy systems often don’t allow for modern test automation. During the modernization process, we implement unit and integration tests so you’ll know right away when you break something in the future.

Yes.  More than likely your existing application was constructed before responsive web development (RWD) and/or progressive web apps (PWAs) were the norm or before your prior software team was skilled in their use.  All MercuryWorks development utilizes RWD interface construction techniques; your modernized application will work on a range of devices including desktops, laptops, tablets and smartphones.
