Application Migration

Micro Focus is the preferred tech partner to help migrate and modernize over 1,000 Enteprise COBOL and Mainframe application projects.

Migrate 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 legacy architectures you are not building for the future.

Application Migration, also referred to as "application rehosting" represents safe and cost-effective application 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 migration. 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 Awkward, outdated technology was never designed to support today's rapid pace of business change, let alone the next wave of technology – cloud, mobile, next-generation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.
