Before rolling back, stop the software being rolled back. For example, if you are rolling back to a prior version of WebSphere application server, you will stop the application server.
In Installation Manager, select Roll Back.
Select the package that you want to roll back. In this example, the WebSphere application server is selected.
Select the version you want to roll back to. In this example, the application server will be rolled back to version 184.108.40.206. You can only roll back to prior versions that were installed. For example, if you are at version 220.127.116.11, and you want to roll back, a prior version such as 18.104.22.168 must have previously been installed on the system.
Select Roll Back.
You can now start the software that was roll back. In this example, you would start the application server.
