javascript - Upgrading jQuery Library form 1.7.1 to 1.10.1 not working

Question

I have developed a web application by using jQuery 1.7.1. Now I am trying to switch to jQuery 1.10.2 but it isn't working.

Upon using the latest version, none of my existing jQuery code works.

I am using the Google-hosted version of jQuery:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

Is it OK to stay with 1.7.1? How can I upgrade to 1.10.2?

I am getting the following messages in my browser's console:

Use of Mutation Events is deprecated. Use MutationObserver instead.

The Web Console logging API (console.log, console.info, console.warn, console.error) has been disabled by a script on this page.

jquery-migrate: Migrate older jQuery code to jQuery 1.9+

Migrate is a best solution I found
