 The following diagram shows the migration paths that customers may take depending on the current platform, tooling, and experiences available to them.

 The current OS and endianness of the platform determines the appropriate tools you will need to migrate your Oracle E-Business Suite to AWS. 

 The following table identifies each tool and its support for homogeneous and heterogeneous migrations. 

 *Table 2 — Migration tools and their support for homogenous and heterogenous migrations*
