Article Title: Stratagies for migrating from Alpha and VAX Systems to HP Integrity Server Systems on OpenVMS
» HTML, » PDF
Article Abstract: The ideal method for migration to OpenVMS on the Intel® Itanium® architecture is to recompile, relink, and requalify. For many users, this strategy has been highly successful. Many
applications, each comprised of hundreds of thousands of lines of source code, have been ported virtually overnight.
Other organizations face more challenging circumstances. Restricted budgets, operational commitments, dependencies on layered products, staff shortages, the sheer number of applications, and the
size of the aggregate source bases make the "all at once" strategy infeasible.
OpenVMS provides unique capabilities that allow an organization to assimilate HP Integrity servers in a phased, structured, extremely low-risk approach. This strategy decouples the different
phases to the maximum extent possible, permitting the assimilation process to proceed transparently to users, with minimal disruption to operations and minimal business risk.
OpenVMS has clustering and image translation capabilities that offer end-user management and technical staff a unique degree of flexibility. In the past, this flexibility has enabled OpenVMS to
confound critics by enabling the assimilation of Alpha processors and, more recently, Intel Itanium processors. The same capabilities that enabled the rapid assimilation of radically different
hardware architectures by the OpenVMS Engineering organization itself are fully available to independent software vendors and end users.
