To the best of my knowledge, there is no de-install tool available
with sr10.x. The Apollo install tool set, RAI (Release And Install),
that was developed for sr10 was planned to have de-install capabilities
but it turned out to be enough trouble that it was dropped. There are
so many ways that a predecessor system could be configured, that to provide
a correct de-install tool, the install tool would have to keep around a
complete copy of your old system after doing an update install.

Please note that you cannot even trust the install "-v" to tell you
all of what is happening to your system during an install. I have been
burned more than once by an install silently changing something that,
IMHO, it shouldn't have. ;{

So the bottom line is: protect yourself with a backup before doing a
major system install, or try it out first on an expendable machine.
