12.5 Reverting to an Earlier Software Load
True Revert allows the system to revert to the protect system software image and its attendant database.
The reversion does not affect DCC connectivity or traffic on circuits provisioned prior to the activation
of the working software load. All versions of ONS 15327 software support this feature.
The ONS 15327 supports a working and protect software version on each XTC. The protect software
version saves the provisioning that existed when the working load was activated. This means that the
protect software load can only reinstate the circuits provisioned before the working load was activated.
Circuits provisioned after the activation of the working load are lost during a revert.
When you click the Activate button after a software upgrade, the XTC copies the current working
database and saves it in a reserved location in the XTC flash memory. If you later need to revert to the
original working software load from the protect software load, the saved database installs automatically.
You do not need to restore the database manually or recreate circuits.
