<p>I need to upgrade my current version of DNN this week. I am currently using 2.1.1. I don't want to do everything twice, so, I have several questions.</p>

<ol>
<li>Is there an upgrade tool or some scripts somewhere that will help me to do an upgrade.</li>
<li>Am I better off installing 4.9 or 5.0. It is production.</li>
<li>If I go with 4.9, will I be able to upgrade to 5.0 when it releases?</li>
</ol>

To be honest, I don't know.  But I see that the DNN download page very strongly states that the 5.0 release-candidates are "NOT RECOMMENDED FOR PRODUCTION USE".
