According to the man page, upgrade = update --obsoletes

It also says it is more suitable to use for distrobution upgrades, like
changing from somelinux 8.0 to somelinux 9.

Amazing what you can learn by reading a man page.  B^)

It is my understanding that some changes were made recently that allowed
for package obsoletion more readily during an update, which renders the
difference pretty much moot these days.  I could be wrong about this
though.  I've had certain packages removed during an update and be
replaced by new ones with different names.
