You can have more than one Zope 3 installed, e.g. you can install Zope
3.2.1 in parallel to 3.2.0 and switch your instance over to 3.2.1 (by
editing the start scripts in $INSTANCE/bin). You can also install Zope
3.2.1 into the place where 3.2.0 was installed; your instance should
continue to work. Such a thing isn't recommended when upgrading between
major versions, though (3.2 to 3.3).
