The revert feature is useful if a maintenance window closes while you are upgrading CTC software. You
Tip
can revert to the standby software load without losing traffic. When the next maintenance window opens,
complete the upgrade and activate the new software load.
Note Provisioning performed after a software load is activated (upgraded to a higher software release) will
not reinstate with a revert. The database configuration at the time of activation is reinstated by a revert.
This note does not apply to maintenance reverts (for example, 2.2.2 to 2.2.1), because maintenance
releases use the same database (a revert to a maintenance release software load will use the current active
database; therefore, no provisioning is lost).
Complete the
Step 1
revert. If you are already logged in, go to Step 2.
Record the IP address of that node. The address can be obtained using one of the following methods:

the software reversion has taken place.

This procedure reverts the ONS 15327 database to an earlier software
load. Reverting to a R3.3.0 or later load will switch to the older software
load and its database without affecting traffic or DCC connectivity.
This feature requires dual XTC cards
This feature requires Software R3.3.0 or later as the protect version.
