Analyst(s): Richard Jones

Summary

Difficult economic times and extremely tight budgets have IT organizations questioning the old adage: "If it ain't broke, don't fix it." Reduced instruction set computer (RISC) customers trying to react to the IT budget crunch are tantalized by the prospect of lower costs that may be achieved by moving to x86-based platforms. But can cost savings be achieved in all cases? And what's the best approach to planning and accomplishing a RISC-to-x86 platform migration? In this Burton Group assessment, Service Director Richard Jones outlines the planning and migrating steps for moving proprietary RISC hardware systems to open x86 systems.
