then you understood wrongly... 
"apt upgrade" does a full upgrade of installed packages... including
installing missing packages to fulfill new dependencies...

in apt-get this function was split out into the "dist-upgrade" command,
while "upgrade" only upgraded existing packages and held back the world
when needing additional new dependencies ... this latter behaviour led
for example to people being stuck on old kernels with security holes
when they only ever used "apt-get upgrade" ... 

the new "full-upgrade" will simply additionally also remove packages
which the normal "upgrade" function would not do.

there is not and has never been any apt or apt-get command that could
lead to a full release to release upgrade without you doing additional
changes manually ... like changing the content of the souces.list file
or using the release upgrader tool (update-manager on the desktop or
do-release-upgrade on cmdline). this has not changed ...
