This document discusses approaches for migrating data from Oracle's Financial Data Management Enterprise Edition (FDMEE) to its successor product, Oracle's Financial Data Management Enterprise Edition (FDMEE). It outlines two main approaches - using Oracle's migration utility or doing a full rebuild. The migration utility uses Oracle Data Integrator (ODI) under the hood and can automate some but not all aspects of the migration. A full rebuild takes more time but allows for cleaning up of unused artifacts and other improvements. Best practices are discussed such as designing the target system structure, rebuilding scripts with Jython, and thorough testing.
