The Upgrade Assistant readiness check performs a read-only, pre-upgrade review of your existing Oracle Fusion Middleware schemas and Oracle WebLogic configurations.
The readiness check generates a formatted, time-stamped readiness report so you can address potential issues before you attempt the actual upgrade. If no issues are detected, you can begin the upgrade process. Oracle recommends that you read this report thoroughly before performing an upgrade.
For more information, see the Sample Readiness Report..
Note:
Alternatively, you can run the readiness check in -response mode to perform a silent readiness check using a response file. For more information on using a response file with the Upgrade Assistant, see Starting the Upgrade Assistant in Response File Mode.You can run the readiness check while your existing Oracle Fusion Middleware domain is online (while other users are actively using it), or offline.
Readiness checks can be run any number of times before any actual upgrades are attempted. However, do not run the readiness check after an upgrade has been performed, as the report will not provide valid results.
Note:
Oracle recommends that you run the readiness checks during off-peak hours to prevent possible performance degradation.
