Comment(by drkirkby):

 I've long since thought that we need a way of stopping people upgrade from
 incomatible versions. One stratergy might be to only allow upgrades of the
 same major version, then ensure that incomatible changes are not permitted
 in the same version.

 I've personally given up tryig to use the upgrade option.
