Mainframe Rehosting

In many cases, the lowest cost, lowest risk solution for migrating mainframe workloads is through rehosting to open systems. Since rehosting is focused on simply changing hosts, or platforms, it allows you to maintain existing applications with very little source code modification. These applications are recompiled to run in a new environment using Unix, Linux or Microsoft Windows.

Rehosting: Lowest risk, lowest cost

Rehosting offers several distinct advantages over other mainframe modernization alternatives:

• The mainframe environment is replicated on a new, lower cost platform. Cost savings of 50% to 70% or more are common.
  
  
• Existing business logic is preserved - very little source code modification is typically required. This greatly reduces risk and cost, and ensures that there will be virtually no impact on day-to-day business operations.
  
  
• Most code conversion is accomplished using automated tools and utilities.
  
  
• The rehosted applications can usually run natively on the new platform.
  
  
• Legacy applications can be easily integrated with new technologies such as web services.
  
  
• Extensive retraining of valuable personnel is not needed - current skill sets can be reused. This minimizes disruptions to existing teams and workflows.
  
  
• Rehosting projects are typically accomplished quickly and provide a quick return on investment. While the process is highly dependent on code complexity, most projects are completed in less than 12 months and can provide a ROI within 18 months.

Mainframe rehosting does not eliminate your COBOL code. Elimination of this code is not the goal of mainframe rehosting. More importantly, rehosting prepares you for transfer and transition. With rehosting, you can quickly and safely transfer your existing mainframe environment to a much lower cost platform. You can also prepare for the transition to a next generation system by eliminating expensive, proprietary hardware and software. This cost savings alone is often enough to fund a longer-term project to develop, or purchase, all-new applications.
