title: change the language of a sitecore item(tree)?
body: <p>We have a small website which was developed with the default language ('en'), without paying mind to the language or versioning capabilities of sitecore (ouch!). We simply forgot to set the correct default language at the start of the project.</p>
  
  <p>Now we have an entire content tree of 'en' items, when they should be 'nl-NL' (it's a Dutch site). And I am wondering if there is an easy way of changing the language for all items in that tree (that does not involve hacking). </p>
  
  <p>I found <a href="https://stackoverflow.com/questions/1705006/sitecore-set-change-default-language-from-en">this Q&amp;A</a>, but it just talks about setting the default language. I'd like to do that, yes, but I would also like to set the correct language for the existing item(versions).</p>
  
  <p>thoughts?</p>
