Chris Dunn, lead technical consultant at Perficient, recently wrote a blog post on how to migrate an Oracle Hyperion Planning application. His blog provides a single, concise process for migrating EPMA enabled Planning applications between two spearated environments. He makes a few assumptions during the process, but details them and the Oracle specific references he used.
The overall process uses a couple technologies to accomplish the migration of Planning applications, the underlying Essbase database and its artifacts, EPMA metadata, and the Reporting and Analysis repository.
