Rehost to Refresh Your Application Architecture and Build for the Future

Your enterprise applications underpin your business. But too often they’re locked away within a complex IT infrastructure, and if your applications are trapped on older architectures you are not building for the future.

Rehosting, often referred to by industry experts as "application migration" or "replatforming," represents safe and cost-effective modernization. It is the key to unlocking the value within your core business systems, reducing your total cost of ownership and delivering new functionality faster.

Micro Focus is the industry leader in application rehosting. Our track record in delivering fast, easy, and cost-effective application modernization, supported by high-quality, proven technology, is unrivaled.

The Challenge With Modernizing Enterprise COBOL Applications

Even though long-established COBOL applications are powering the core system operations supporting today’s business, IT strategy is always focused on next-generation investment.

The cost, complexity, and risk needed to deliver business change requirements will only continue to increase as a consequence of this shifting focus, decline in investment, and growing uncertainty around skills and resource availability.

The core issue is often not with the application itself, but with the rigid infrastructure surrounding it. Awkward, outdated technology was never designed to support today's rapid pace of business change, let alone the next wave of technology – cloud, mobile, next-generation architectures – that few could have predicted when writing the original code.

A new approach is needed.
Enterprise COBOL Application Rehosting for Higher Performance

Application rehosting redeploys your current application logic on a new, modern platform. With Micro Focus, contemporary development tooling supports and maintains it within a distributed architecture.

Organizations with mainframe and mid-range COBOL environments can realize multiple benefits through a successful application rehost using Micro Focus solutions. They include:

Application performance gains of up to 75%

Cost savings of up to 90%

Development productivity gains of up 30%

A proven pathway towards attracting next-generation skills

For Systems Integrators (SIs) and modernization partners, the Micro Focus rehost solution represents industry-leading technology for projects of any size.
