title: ClickOnce check updates starting from next version
body: <p>A bit of background: my company is moving file distribution server names for whatever reason. We publish all our apps to <code>\\SrvA\distribution</code>, and starting Monday the server will change name to <code>\\SrvB\\distribution</code>, with no period of overlapping names. It's the same physical server, but the name is different.</p>
  
  <p>Now, publishing to <code>\\SrvA\distribution</code> is trivial, I set the Publishing Folder Location to the correct path on it and everything else is left blank and it just works.</p>
  
  <p>What I want to do is publish an update on <code>\\SrvA\distribution</code> right now that will make ClickOnce check the new location instead from then on. It will do nothing until Monday when the new server is up and it can get the next new version with the <code>\\SrvB\distribution</code> publish path and everything will work fine.</p>
  
  <p>What actually happens if I set the update path to <code>\\SrvB\distribution</code> however is that it's checking it <em>before downloading the application</em>, thus finding nothing (the path doesn't exist). And Monday, when the old file server is going to be down, there will be no link to forward it anymore, so this solution won't work.</p>
  
  <p>I also can't do anything about the server migration procedure, so any solution will have to be done in code.</p>
