title: How to install / upgrade Appium 1.6.3 / 1.6.x with Appium Version Manager
body: <p>Appium 1.4.16 or any 1.4.x version works fine. We used Appium Version Manager (avm) to upgrade to new versions, but with 1.5.x onwards does not seem to be working.</p>
  
  <p>I am currently on Appium 1.4.16 and would want to upgrade to Appium 1.6.3 (current latest). Can we do that?</p>
  
  <p>Note - the reason we need avm is to switch between appium versions, which i feel is good to have. Helps us specially when we are in the process of upgrading our suite to cater the changes in 1.6.x, so that until we finish, we can still use an older (stable) version</p>
