Downgrade R80.20 to R80.10 through clish

[Sokre]

Hello,

as described in the subject, is it possible to downgrade R80.20 to R80.10 through clish (i only have console access)?

I'm aware about creating and running First Time Configuration Wizard template through clish but don't see any option there for downgrade (as same kind that is available on FTCW through WebGUI).

Thanks!
