It depends, you can upgrade in-place by building, but you might as
well delete the old install and replace it by a new version.

Yep - you can also have various Sage installs in parallel - they are
all independent of each other.

~/.sage should not create trouble on upgrade. If you run some ancient
version of Sage (i.e. 1.0 for example) it doesn't get along too well
with Sage 3.2 and higher, but other than that there are no known
problems.
