I currently have   the following references to jquery in a web form 2010  application where I updated the main jquery reference:

  <script src="../scripts/jquery-3.2.1.js" type="text/javascript"></script>
   <script src="../scripts/jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script>
    <%If (False) Then%>
        <script src="../scripts/jquery-3.2.1.js" type="text/javascript"></script>
    <% End If%>    
    <script src="../scripts/site.js" type="text/javascript"></script>
    <script src="../scripts/json2.js" type="text/javascript"></script> 
    <script src="../scripts/jquery.validate.pack.js" type="text/javascript"></script>
   <script src="../jquery-ui-1.7.2.custom.css.js" type="text/javascript"></script>

Due to that fact, I have the following questions to ask you:
1. If I change the main jquery reference to point to the current version of jquery (query-3.2.1.js), will I need to change any of the other references that I listed above? If so,
what jquery scripts would I need to change and would you know why I would need to change them?
2. If I change the jquery-ui-1.7.2.custom.min.js file to use the current version, will I need to change any of the other references that I listed above? If so,
what jquery scripts would I need to change and would you know why I would need to change them?

3. If I left all the jquery files to their original (current versions) would I eventually have a problem with the jquery references? If so what reference would you change? if not, you are saying that everything should continue to work correctly?
