Look into makedeltaiso and applydeltaiso. You end up needing the
original (previous release/target) and the delta. This is only useful if
the old ISO is left around and you want to end up with a full ISO on the
other side. The size of a delta ISO between Fedora releases might be
larger then expected. It would be interesting to see some data on this
matter.
One can use a script such as the rawread script at
http://www.troubleshooters.com/linux/coasterless.htm
to read an ISO off an optical disc. So the original ISO(s) can be read
off the original install media, if one has those. Or one can just make
a point of keeping the original ISO(s) on the HD after installing. And
even if the size of the deltaiso was 60% or 70% of the full ISO, it
would still be worthwhile to many.
