Sandblast appliance Downgrade from R80.10 to R77.30

[Suresh_Kumar_K]

Can we downgrade from R80.10 to R77.30

If so can I directly downgrade..

Theoretically you could reinstall with R77.30 image if you have one or revert to R77.30 snapshot, once more, if you have it. 

Check Point does not have any downgrade procedures apart from roll back regressions during a failing upgrade process.

Make sure to use the T5 image and the latest ISOmorphic, create a USB stick and do a clean install from USB.
