    You should look at the Official Sencha migration guide first. From there, you should identify specific parts of your application that are breaking. If it is a layout issue, start commenting out individual panels one at a time to find the problem. Once you’ve identified the panel with the layout issue, start commenting out individual widgets that might be causing the issue.

    You should also take advantage of your debugging tools such as Firebug. Use the call stack navigator. You may be able to use it to locate the specific control with the problem.

    EDIT: official guide is gone from the interwebs… try http://www.sencha.com/forum/showthread.php?70352-Upgrading-to-Ext-3
