title: How to merge with SVN server prior to 1.5 (retrieval of mergeinfo unsupported)?
body: <p>Locally I've got <code>TortoiseSVN</code> version 1.6.11 installed.</p>
  
  <p>This is using Subversion 1.6.13</p>
  
  <p>My central SVN repository uses version SVN Server version 1.4.2 (and I can't upgrade it).</p>
  
  <p>Every time I try to merge I get the message:</p>
  
  <pre><code>retrieval of mergeinfo unsupported by http://svn01.xxx.xxx.com/svn/
  </code></pre>
  
  <p>This is because the server uses an older version of SVN, which doesn't support mergeinfo, meaning my local version won't work.</p>
  
  <p>So how can I merge?</p>
