Not with 100% safety.  If the upgrade is small (e.g. 5.3-RELEASE to
5.3-RELEASE+security patches), then you can often get away without
needing single-user mode.  If you're trying to upgrade to a new
version, this becomes increasingly dangerous.

And in any event you need to have a recovery plan thought out, for the
cases when something goes wrong.

Yes.
