Downgrading the Sensor

Caution You cannot use the downgrade command to revert to a previous major or minor version, for example,
from Cisco IPS 7.0 to 6.2. You can only use the downgrade command to downgrade from the latest
signature update or signature engine update. To revert to 6.2, you must reimage the sensor.
Use the downgrade command to remove the last applied signature upgrade or signature engine upgrade
from the sensor.
To remove the last applied signature update or signature engine update from the sensor, follow these
steps:
Step 1 Log in to the sensor using an account with administrator privileges.
Step 2 Enter global configuration mode.
sensor# configure terminal
Step 3 If there is no recently applied service pack or signature update, the downgrade command is not
available.
sensor(config)# downgrade
No downgrade available.
sensor(config)#
