You are involved in a project to upgrade to Oracle E-Business Suite, Release 12. You need more information about the upgrade processes and paths. Where would you find the upgrade guide for Oracle E-Business Suite?

The primary official repository for Oracle E-Business Suite Release 12 upgrade guides, upgrade paths, technical documentation notes, and patch information is the MetaLink Knowledge Base (now integrated into My Oracle Support). Oracle publishes comprehensive upgrade documentation—including specific upgrade instructions, prerequisites, and certified paths—in MetaLink knowledge documents (such as Note 396009.1) to guide administrators through the technical upgrade process.

A. AppsNet is a legacy sales/partner program portal, not the official technical documentation repository for upgrade guides.
B. The Bug Database tracks software defect reports and bug fixes, not comprehensive end-to-end product upgrade guides.
C. Technical Forums provide community discussion threads rather than authoritative, certified Oracle upgrade guides.
E. While general product documentation exists on OTN, official EBS release-specific upgrade notes and patch documentation reside on MetaLink.
F. Customer Knowledge Exchange is a community user group discussion portal, not the source of official Oracle upgrade manuals.
