March, 2005
Using a fictional case study that draws from several actual customer migration projects, this Sun BluePrint article illustrates the methodology, tools, and best practices used to migrate an HP/UX environment to the Solaris environment. The most significant of these projects, for a large health care insurance provider based in the United Kingdom, involved migrating a commercial-off-the-shelf (COTS) integrated-accounts solution to the Solaris Operating System (Solaris OS), and enhancing it to support their risk-underwriting and claims-processing business functions. This article provides an overview of the case study; descriptions of justifying, architecting, and implementing the migration; suggestions for managing the new Solaris environment; and a summary of the successful results of the migration.
