Diffconfig - defconfig - .config

stupid question here.
I have a .config file, build after hours and hours of click-here-and-there in menuconfig, is there a way to create the diffconfig file starting from my full config file?
I get a "out of sync" warning when i build using my old config file (that i fix entering menuconfig and saving changes), so i assume the correct way would be having a diffconfig and create the new config at each use..

scripts/diffconfig.sh > diffconfig-file-to-write

Note that there should be an automatically created file config.buildinfo next to your built firmware, so you can skip manually creating such file.
