View Full Version : How hard can it be an "urgent" migration from 3.0.0 to 3.4.x?

Recently (3 months ago) I have started this job taking over maintenance of an application that uses Ext 3.0.0.

I have my hands full with the app bugs and I wanted to wait to have it more stabilized to upgrade extJs (to begin with, to 3.4.x), but I found myself wanting to use some components that are not part of 3.0.0 (like http://dev.sencha.com/deploy/ext-3.4.0/examples/multiselect/multiselect-demo.html).

How difficult is supposed to be if I just swap the libraries in my application with the 3.4.0 version? Will it be likely to break the current JS?

Thanks in advance

I don't think there's a general answer here. It is preferred to upgrade more frequently, but you may have a smooth upgrade depending on what your code looks like. Can you test your code against 3.4.x to see how it performs?

It basically shouldn't trigger much problems. Are you using many ux? Then try to get the lates versions from them aswell.
