Overview of the Active Upgrade Process
•Test the latest software updates in your environment before making the updates permanent.
After your critical applications are restarted on the upgraded software, you can verify the success of your software updates in a production environment, with real users and system load. If you want to keep the changes, there is no additional downtime. Otherwise, as quickly as your system can restart, you can abort the upgrade to go back to the original version of your software.
•Abort the upgrade process at any point, until you commit the changes.
If, for any reason, you are not satisfied with an upgrade, you can abort the upgrade session to return the system to its original state. Nothing is permanent until you choose to commit the changes. (Also, if you abort the upgrade early enough in the process, before testing the software in your production environment, your critical applications are not disrupted.)
