Redmine 버전 upgrade 오류 사항

나는 Redmine 1.3에서 2.3.1로 upgrde를 했는데

ActionView::Template::Error (The single-table inheritance mechanism failed to locate the subclass: 'Subversion'. This error is raised because the column 'type' is reserved for storing the class in case of inheritance. Please rename this column if you didn't intend it to be used for storing the inheritance class or overwrite Repository.inheritance_column to use another column for that information.):

와 같은 오류를 만났다.

repositories 테이블에 있는 데이터를 지우고 다시 했더니 오류가 해 결되었다.
