Patches to upgrade from Oracle Apps 11i to Oracle Apps R12
Upgrading from Oracle Applications Release 11i to Oracle Applications Release 12 just got a lot easier: identifying patches for the upgrade process itself. These pre-install patches help you avoid certain upgrade script failures, upgrade performance issues, and data corruption and upgrade integrity issues.
The new Oracle E-Business Suite Pre-install Patches Report provides a single list of essential patches that you must apply in pre-install mode before upgrading from Oracle Applications Release 11i to Oracle Applications Release 12.1. This report serves as a single point of reference for upgrade-related patches that can ONLY be applied prior to running the main upgrade driver for Oracle Applications Release 12.1. The report also includes links that take you directly to the patches you want to download.
