So this message isn't actual dangerous?
How can I rollback if I faced any issue using this snapshot.

Confirm the steps please

You can ignore that and proceed with the upgrade by using the 'no-validate'
option.  As a precautionary measure, you might want to take a snapshot of
the system prior to upgrading, in order to ensure proper rollback should
hell ensue - 'request system snapshot'.
