title: Upgrading Subversion server from 1.5.5 to 1.6.5 - dump/upgrade/reload, exact steps?
body: <p>I'm about to upgrade a SVN server from version 1.5.5 to 1.6.5 - all is fine with the actual upgrade, but I'm a little confused about upgrading the actual repositories. </p>
  
  <p>I've read in a few places (<a href="https://stackoverflow.com/questions/1160761/how-to-upgrade-svn-1-4-4-r25188-to-svn-1-6/1161408#1161408">here</a>, <a href="http://svnbook.red-bean.com/en/1.5/svn.ref.svnadmin.c.upgrade.html" rel="nofollow noreferrer">here</a>), that it's better to dump and reload the repositories rather than using <code>svnadmin upgrade</code>. I assume that I should dump, upgrade the server and then load the dumps back in - however, should I clear the old files out of the repository before loading? If so, what's the best way to do this?</p>
  
  <p>If, before I thoroughly screw up my version control system, someone could give me a quick step-by-step, it would be really helpful!</p>
  
  <p>Cheers, 
  Mark</p>
