Hello community,

I need to downgrade CSS 11501 software from 08.20.8.01 to 08.20.3.03

I used the command: # upgrade "sg0820303.adi"

After reboot I have:

CSS11501# sho ver
Version:               sg0820303 (08.20.3.03)
Flash (Locked):        08.10.1.06
Flash (Operational):   08.20.8.01
Type:                  PRIMARY
Licensed Cmd Set(s):   Standard Feature Set

Version is ok, but what about the  "Flash (Operational):   08.20.8.01" section? Is there a way to restore to version 08.20.3.03?

Thanks

Lucas
