CHAPTER 10
Migrating to the Exadata Database Machine

Up until now, we’ve covered the features of the Oracle Exadata Database Machine and the best practices for using it. If you are creating and deploying brand-new databases on this platform, you would have all the information you need. But there are an enormous number of existing databases and applications that can benefit from the Exadata Database Machine, which means that you will have to perform a migration to this new platform.

This chapter discusses the best practices and methodologies for migrating from Oracle and non-Oracle relational database sources to the Exadata Database Machine. In general, the methodology and steps required for such migrations depend on the source database and version, the hardware platform, and the operating system. You should remember that the process for migrating to the Database Machine is no different from the process of migrating to a regular Oracle Database 11g Release 2 on a Linux x86-64-based or Solaris-based platform configured with RAC and ASM. There are no special steps in the migration process that are specific to either the Exadata Storage Servers or to the Database Machine.
