title: SVN how upgrade working copy
body: <p>I use STS for working with SVN. When I try upgrade (version 1.6) I received this error:</p>
  
  <pre><code>org.apache.subversion.javahl.ClientException: Invalid operation on the current working    directory
  svn: Can't upgrade 'C:\..... as it is not a pre-1.7 working copy directory
  </code></pre>
  
  <p>Can't find an entry
      svn: Missing default entry
  But is sure that missed - I have add new folder.
  How it can be resolved? Thanks.</p>
