In addition to this document, Oracle provides information about upgrades on its support site, and through the AutoUpgrade utility using the preupgrade parameter.

Through its support website, My Oracle Support, Oracle provides late-breaking updates, discussions, and best practices about preupgrade requirements, upgrade processes, postupgrade tasks, compatibility, and interoperability.

Before you begin upgrades, Oracle strongly recommends that you download the latest version of the AutoUpgrade utility, which is available on My Oracle Support. The latest version contains the most recent checks and tests that Oracle can provide to assist you to prepare your system for upgrades, and to complete upgrades successfully. You can perform your upgrades directly using AutoUpgrade. If you do not use AutoUpgrade to perform the upgrade, then to identify potential upgrade issues, you must run AutoUpgrade using the preupgrade parameter in analyze mode. This AutoUpgrade option replaces the Pre-Upgrade Information Tool that you may have used in earlier releases.

Mike Dietrich's blog site, "Upgrade Your Database Now," Daniel Overby Hansen's site, "Databases Are Fun," can offer you the most current insights from the upgrade and migration product managers for Oracle. Their opinions and recommendations are based on their experiences and interactions with Oracle customers, and can save you time and effort. They are highly recommended.
