Legacy Modernization — a Small Guide

It is important for organizations to constantly update their legacy systems, to cope up with the changing trends in their field of business. Implementing transformations or incorporating legacy modernization strategies not only helps reduce costs and complexities of the IT environment, but it also boosts the consistency of data.

By bringing in a fundamental shift in application architecture, legacy modernization integrates cutting edge technologies into the existing infrastructure. The main aim behind the use of legacy modernization strategy is to improve customer experience. However, in the cases when the business has changed to extents, where the old applications no longer serve the purpose, the modernization procedure will have to address the entirety of it.

The Different approaches available

When opting for a legacy modernization, a company should get its resources evaluated. This will include things like determining their values and their potentials of merging with the new resources. When opting for legacy modernization, there are generally the following options that are available to the company –

Screen-scraping

This provides the legacy application with a modern looking interface. It can be brought about without updating the old application.

Code conversion

When the programming language of the application gets outdated, it needs to be converted into a modern programming language and this is what code conversion is about.

Rip and replace

Often used when training new staff, this implies the removal of the old application and replacing with one that has everything new, from database to programming language, to address the recent business needs.

Buy new and migrate

Unlike the rip and replace process, this uses a pre-built application package. It further requires a transfer of data to the new platform.

Extend and surround

This approach allows the modernization of certain aspects of the existing application, when the need arises.

It is important that you understand the modernization process well, in order to make an informed decision.
