  <h2>Option 1</h2>
  <ol>
  <li>Duplicate the .prproj file you want to downgrade and name it <code>temp_downgrade.prproj</code> or something. Just so you don't have to mess with the original.</li>
  <li>Download 7zip.</li>
  <li>Right click on <code>temp_downgrade.prproj</code> and select <code>Extract here</code>.</li>
  <li>You should see <code>temp_downgrade</code> next to the original temp file with no <code>.prproj</code>.</li>
  <li>Now right click on the <code>temp_downgrade</code> file and open it with a text editor.</li>
  <li>You should see a couple million lines of confusing text, ignore it. you are looking for the 4th line, it will look like this:
  <ul>
  <li><code>   &lt;Project ObjectID=&quot;1&quot; ClassID=&quot;62ad66dd-0dcd-42da-a660-6d8fbde94876&quot; Version=&quot;29&quot;&gt;</code></li>
  </ul>
  </li>
  <li>That <code>version=29</code> (or whatever it says in your file, could be any number) is what you have to change. Simply set it to <code>1</code> so the whole line reads:
  <ul>
  <li><code> &lt;Project ObjectID=&quot;1&quot; ClassID=&quot;62ad66dd-0dcd-42da-a660-6d8fbde94876&quot; Version=&quot;1&quot;&gt;</code></li>
  </ul>
  </li>
  <li>Save the changes you've made to the file.</li>
  <li>Now right click the <code>temp_downgrade</code>file - remember the one without the <code>.prproj</code> - extension and select <code>add to archive</code> under <code>7zip</code> .</li>
  <li>Change archive format to <code>gzip</code> and change the file name to be something. like <code>temp_downgraded.prproj</code>. Doesn't really matter it must end in <code>.prproj</code> though.</li>
  <li>That's it open <code>temp_downgraded.prproj</code> like a normal premiere project and it'll ask to upgrade the file or something. Save the copy somewhere permanent as that's where any changes you make will be saved. You can delete all the temp files now.</li>

  <h1>Are there any consequences from doing this?</h1>
  <p>Not reeeeeally. At least - it's much less than the current accepted answer on this thread. If you export something as an xml file on premiere you will effectively lose most of the editing you've done. Aside from maybe the most basic sequences. All the colour correction, Sound work, etc is gone. With this method - yes some of that will disappear if you are working on an old enough version of premiere. But, I'm talking like five years old. If the difference is CC2017 and CC2016. Sure you'll lose any effects that only exist in CC2017. But I would bet this is mostly niche stuff and <strong>99.999% of your project will probably be fine!</strong> But - even if it isn't - say you make some small changes to your downgraded version on CC2016. If you copy the downgraded version to a computer with CC2017, after the changes have been made. All the newer features will still be there. So as long as you render on the computer with CC2017 nothing will be lost.</p>
  <p><strong>tl;dr: Obviously there are some cases where you could lose information, but if you just need to make minor edits or fix something small on your home computer then take it back to work or something - this is fine.</strong></p>

  I think your best option would be to **[export your sequence as an XML](http://help.adobe.com/en_US/premierepro/cs/using/WScbecf3f614eb38be7a1f773012504357269-8000.html)**.

  ## Option 1
  
  1. Duplicate the .prproj file you want to downgrade and name it `temp_downgrade.prproj` or something. Just so you don't have to mess with the original.
  2. Download 7zip.
  3. Right click on `temp_downgrade.prproj` and select `Extract here`.
  4. You should see `temp_downgrade` next to the original temp file with no `.prproj`.
  5. Now right click on the `temp_downgrade` file and open it with a text editor.
  6. You should see a couple million lines of confusing text, ignore it. you are looking for the 4th line, it will look like this:
     * `<Project ObjectID="1" ClassID="62ad66dd-0dcd-42da-a660-6d8fbde94876" Version="29">`
  7. That `version=29` (or whatever it says in your file, could be any number) is what you have to change. Simply set it to `1` so the whole line reads:
     * `<Project ObjectID="1" ClassID="62ad66dd-0dcd-42da-a660-6d8fbde94876" Version="1">`
  8. Save the changes you've made to the file.
  9. Now right click the `temp_downgrade`file - remember the one without the `.prproj` - extension and select `add to archive` under `7zip` .
  10. Change archive format to `gzip` and change the file name to be something. like `temp_downgraded.prproj`. Doesn't really matter it must end in `.prproj` though.
  11. That's it open `temp_downgraded.prproj` like a normal premiere project and it'll ask to upgrade the file or something. Save the copy somewhere permanent as that's where any changes you make will be saved. You can delete all the temp files now.
