There's actually advice in the release notes to that effect (along with other
strategies for freeing or finding necessary space):

https://www.debian.org/releases/stable/amd64/release-notes/ch-upgrading.en.html#package-status

A command can be run that supposedly will warn the constrained user if
she hasn't enough room on disk for the upgrade (this after modifying the
/etc/apt/sources.list file to point to Stretch and running apt(-get)
update

 apt-get -o APT::Get::Trivial-Only=true dist-upgrade

This failed to work as promised in my case (or I failed somehow
somewhere along the line), and I ran out of room during my upgrade, but
bungled through. I will spare the forum the gruesome details of my
struggle.

The release notes even give detailed instructions as to how you might mount
bind (or is bind mount?) a usb key as a temporary /var/cache/apt/archives
directory.

Good luck.
