>From a practical standpoint, I'd say no upgrade method is particularly
supported in reality. The extent of our support is that we test that an
upgrade from a completely clean install of the previous release works;
that's all the guarantee you get. There's no planned testing of upgrades
from any kind of non-stock install, and there's a fairly high bar on
upgrade issues constituting release blockers. In practice, we don't
really try that hard to produce a really reliable upgrade process. We
*state* that anaconda and preupgrade-based upgrades are supported, but
as a project we don't put a huge amount of effort into actually making
sure they work in most cases. (This is partly, of course, because it's
an extremely difficult thing to do.)
