use jquery migrate plugins

use jquery migrate plugins

I have a vb.net 2010 webform application that uses the original jquery libraries. I plan to upgrade to the 1.9 version and followed by the upgrade to the 3.0 version.
I am thinking that I need to obtain the jquery core library to use as a reference to my scripts.

Basically my reference to scripts are in the following order right now:

    <script src="../scripts/jquery-1.3.2.js" type="text/javascript"></script>
    <script src="../scripts/jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script>   

I am thinking that I need to change the references to point something like the following to upgrade to the 1.9 version first.

    <script src="/scripts/jquery-1.10.2.min.js" type="text/javascript"></script>
    <script src=" /scripts/jquery-migrate-1.2.1.min.js"></script>
    <script src="../scripts/jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script>   

Basically the jquery 1.9 core library needs loaded first and then followed by the migrate 1.9 version, correct?
Is this is not correct, what needs to be changed and how would I make the change?

If this correct, where would I obtain the 1.9 core jquery code to download from the jquery.com website?
** I am asking this question since when I go to the main page to download the latest version of jquery, only the 3.2.1 version is available to be downloaded.
