The magic invocation on the command line at the boot prompt is
"upgradeany".

Did a system this way, and the upgrade worked, but ended up doing a
clean install anyway to get rid of accumulated junk from a long upgrade
and 3rd party package install heritage.  My $0.02 is to, if possible
make room for a clean install by freeing space or adding a disk while
keeping the capability to dual-boot the old installation.  Can then
mount the old partitions on the new system to facilitate migration of
configuration files, etc.  Would also have an on-line backup/duplicate
of home directories if possible.  Many changes to user configurations
are not reversible if you have to fall back.
