how to downgrade Sandblast TE appliance from R80.10 to R77.30
A downgrade is not supported - you can do a full re-image, formatting the HD and do a complete reinstallation of R77.30. Everything else depends on your deployment and configuration...
Use isomorphic to create a bootable USB with the R77.30 ISO and install this image on the appliances. It requires complete re-installation and re-initialization of the TE images though.
As the product manager for this product I'm interesting in understanding what is driving this need from your side.
Suresh, could you share why you'd like to downgrade the software version on your TE appliance?
