JackHi, you have to copy paste all the Unraid Files (into the unRAID Server Pro 7.3.0 file) into your USB to update.
copy paste the unraider file in config,
Don't forget to save your go file (in config folder) and paste it in your USB after the update.
I think you can update directly to 7.3.0 because it's the same crack as 7.2.x so i think it will work.
I hope that can help.
