I need to update firmware a USG60 from version 4.20 to 4.73(latest).
What intermediate firmware do I need to perform to prevent the risk of configuration disappearing.

You should be able to to go to latest without risk

backup config is a good idea

thanks for the reply. One more question. How can I clone the configuration from one USG60 (version 4.73) to a backup USG60 (version 4.73)? is it possible to clone the configuration to 100%, or will it need to be further configured after cloning?
