Legacy Modernization

The Legacy Modernization Challenge

Migrating legacy applications to new platforms often involves large, mission-critical applications with countless linkages and dependencies. Such linkages may be tied to other elements on the mainframe, but they could also connect to non-mainframe elements like distributed servers, APIs or databases.

Whether you’re moving your applications off the mainframe or you’re modernizing them in place, the risk of breaking something in a critical process is very real. This is made even more complicated by a lack of sufficient documentation or knowledge loss as SMEs retire.

Make Legacy Modernization Less Stressful

There are three things you can do to reduce the risk and stress of modernizing legacy applications: understand the environment, future-proof the applications with thorough documentation, and educate current and future employees working on the project.
