Console
When the RDR disk resychronization is finished, all critical system resources are
running in duplex mode, and the Active Upgrade process is complete. You do not
need to restart the system, and, because your application is already running on the
upgraded software, there is no additional downtime.

Aborting the Active Upgrade Process
Aborting the Active Upgrade process stops the current upgrade session and returns
your system to its original state. If necessary, you can abort an upgrade session at any
point up until you commit the upgrade.
If you abort the upgrade session while the system is in split mode, no downtime is
incurred. Your applications continue to run on the Production Side while the Active
Upgrade console restores the system to duplex mode.
