Clone your live system, then test, time and document the upgrade procedure, then if everything goes OK in the cloned system it should work as expected in live (and should in theory take less time as you will have documented all the commands etc.).<br>
<br>Going from 2.4 has a number of changes to the GUI interface aswell, so remember your users who will probably be on the phone to you asking where everything is, if you have a cloned system you could give them something to play with for a short period of time before the live is upgraded.<br>

      <br>
      I am concerned with the down time that appears to be involved when
      upgrading from<br>
      2.4.x to 3.0.x when following the procedures outlined in the
      UPGRADING document. Especially<br>
      if after the upgrade we find some showstopper and have to revert.<br>
      <br>
      Anybody have any suggestions to mitigate the risks?<span class="HOEnZb"><font color="#888888"><br>
