As a safety mesurement you could clone the machine ("cp -a") to a
blockdevice on the same remote machine (LVM volume, loopfile) before. If
upgrading breaks anything except remote access, you could run the broken
service inside the chrooted or virtualized clone until you manage to fix
its upgraded version.
