My application is using jQuery v1.8.3 for IE 8 browser, now we decided to upgrade the browser to IE 11, so now current 1.8.3 version is not working properly in IE 8 browser. we decided to upgrade the jQuery version to 1x or 2x.

Following are questions in my mind, could you please clarify the below question.

1. Can we migrate directly from jQuery v1.8.3 to 1.11.3 version ?

2. Is 1.11.3 version supports the IE 11 browser ?

3. Our application is going to use IE 11 browser, so should i upgrade to 1x(1.11.3) or 2x(2.1.4) ?

4. What are the points should i consider while upgrading to higher version ?
