Successfully address legacy software modernization

Today the commercial, organizational and management flexibility required by the market from companies finds an obstacle in too rigid business processes, which are cut on the operational and functional limits of the IT and application supports in use.

Digital modernization collides with obsolete applications, expensive to maintain compared to the latest generation ERP / MRP systems that can be used locally or remotely, both on-premise and in the cloud. Unfortunately, it is not always possible to make a clean sweep of the existing to switch to modern applications and standard processes, based on best practices. We need to adopt gradual changes that accompany the acquisition of new attitudes by people and safeguard the unique processes that express corporate value. This leads companies to consider the path of modernizing legacy software, a process that must take into account business needs, available resources, and ROI, as well as the risks that the company can bear, net of mitigation actions.

A complex process, where technical skills must be side by side with method and experience in defining objectives, stages, and times. To be effective, the application modernization strategy must be studied in synergy with the company’s IT and business operational teams, evaluating, within the application portfolio, what makes sense to modernize, what to keep for some time or to replace, based on the criteria of utility, perspective, and budget constraints.

On a technical level, modernization can consist of the simple addition of interfaces (API, HTTP, and others, to make the legacy application communicate with the modern front-end and services), bringing it to a new platform (rehosting), or updating the basic platform (re-platforming). The goal is often to abandon obsolete systems (AS / 400, Windows NT …) by exploiting standard systems, virtual machines, or the cloud. Other more radical modernization options include code optimization (refactoring), revision of the application architecture up to complete re-engineering (rebuilding) towards microservice architectures.

BinHexS has accumulated a lot of experience in IT modernization projects involving data center and hybrid and multi-cloud migrations. The service desk capabilities that BinHexS can deliver on a 24×7 basis are significant in supporting change.
