by Himesh Bhatt
June 2009
This Sun BluePrints™ article explains the process of moving an SAP environment from one system to another, and describes the resources and services available from Sun to assist users planning a migration.
In general, there are two types of migration: homogeneous and heterogeneous. A homogeneous migration is a migration from one platform and database architecture to the same platform and database. This article focuses on the more challenging type of migration — heterogeneous. This type of migration consists of moving from a non Sun platform to a Sun environment, or from one database architecture to a different database architecture, or both at the same time. In describing the details involved with performing a heterogeneous migration, this article addresses the following topics:
• Challenges and issues
• Assessing requirements and resources
• Creating a plan
• Preparing the infrastructure
• Performing the migration
• Validating the migration
This Sun BluePrints article describes procedures, techniques, and recommendations that can simplify and expedite the migration.
