 ###### Were upgrade and rollback tested? Was the upgrade->downgrade->upgrade path tested?
 
-TBD
+Yes.
+
+When considering only core kubernetes components, and only
+alpha-or-later releases, upgrade/downgrade and enablement/disablement
+create no additional complications beyond clean installs; kube-proxy
+simply doesn't care about the additional rules that kubelet may or may
+not be creating any more.
+
+Upgrades from pre-alpha to beta-or-later or downgrades from
+beta-or-later to pre-alpha are not supported, and for this reason we
+waited 2 releases after alpha to go to beta.
