Update USG60 from 4.33 to 4.73

Giovanni · June 2023

Hi all,
I'm a bit confused. I have a 4.33 firmware on USG60 and I would like to update to the lastest version 4.73. Can I have apply the 4.73 firmware directly or before I need to install the 4.38 then the 4.65 and last the 4.70?

Thanks

Hi @GIOMIND ,

Don't forget back up both device's startup configuration file before you perform firmware update.
