FWIW, IME 18.04 -> 20.04 was smoother than 16.04 -> 18.04.

You could shrink your Windows drive remotely, probably, sure. You can
delete everything in
C:\WINDOWS\TEMP and C:\USERS\&yourusername\Local Settings\TEMP safely.
You can delete C:\PAGEFILE.SYS and C:\HIBERFIL.SYS -- Windows will
just recreate them next time it boots. Then shrink it -- so long as it
has a little space free, Windows will still boot if you need it.

I don't think this will work remotely, but you could boot a live USB
medium, mount the Windows drive, delete the stuff I mentioned, install
PARTIMAGE, and backup your whole Linux system onto the Windows
partition.  Take a full image backup then you can put it back if need
be.

Make backups of /home and /etc and maybe /var _as well_.

I defer to anyone from Canonical here but if you have 11.10 and you
install 18.04 over the top, I think it will leave /home alone and
recreate the user accounts in there on the new installation.

But you'll have to reinstall all your software.

Yes, you could put them side-by-side, sure.

Might help if you mounted your Windows drives too, so we can get an
idea of space on them.

Also, do a ``sudo apt clean`` -- you might get a bunch of free space back.
