Migrating From Tru64 UNIX to the Solaris Operating System 
by Ken Pepple, Brian Down, and David Levy
March, 2005
Using a fictional case study, this Sun BluePrint article illustrates the methodology, tools, and best practices used to migrate a Tru64 environment to the Solaris environment. This study examines the migration of a simple, custom-written application that used a Sybase database to store information about a company's inventory as well as client-specific data. This application was converted to run under the Solaris Operating System (Solaris OS) and was integrated with directory services. Additionally, the database vendor was changed from Sybase to Oracle. This article provides an overview of the Tru64 Unix operating environment; discussions of 64-bit computing and clustering architectures; descriptions of justifying, architecting, and implementing the migration; and suggestions for managing the new Solaris environment.
