Performing a Pre-Upgrade Readiness Check
To identify potential issues with the upgrade, Oracle recommends that you run a readiness check using the Upgrade Assistant before you start the upgrade process.
To run the pre-upgrade readiness check, refer to Running a Pre-Upgrade Readiness Check in Upgrading with the Upgrade Assistant.
When you run the Upgrade Assistant in readiness mode, it performs a pre-upgrade check on the schemas and component configurations associated with a domain. When completed, the readiness check generates a formatted, time-stamped readiness report so you can address potential issues before you attempt the actual upgrade.
Oracle recommends that you read this report thoroughly before performing an upgrade.
If no issues are detected, you can begin the upgrade process.
Note:
Be aware that the readiness check may not be able to discover all potential issues with your upgrade. An upgrade may still fail, even if the readiness check reports success. Be sure to also review the Oracle Fusion Middleware System Requirements and Specifications documentation to ensure your system is prepared to receive the new software version.
