Oracle e-Business Suite Release 12 Upgrade and Platform Migration Guide: HP 9000 to HP Integrity
Source: Hewlett-Packard (HP)
Oracle E-Business Suite is highly configurable and customizable with many customers deploying their own unique environments. For this reason, HP strongly recommends that all migration tasks described in this paper be applied first to a test environment in order to determine application downtime and record any additional steps that may be necessary to properly migrates add-on software, languages, and customizations. Most customers will run through the migration process a number of times on their test environments before finally implementing it in the production environment. Also, additional storage and CPU resources may be required during the migration process, to reduce resource bottlenecks and expedite the effort.
