This PR (https://github.com/umbraco/Umbraco-CMS/pull/2791) merges in a migration altering the
umbracoLanguage table column
languageISOCode. This column is (should be) part of an index and therefore cannot be modified, which causes the migration (and the upgrade) to fail.
Tested on SQL CE - clean install of 7.11.1 upgrading to 7.12.
Backwards Compatible: True
Affected versions: 7.12.0
Due in version: 7.12.0
