Thanks for your reply @Bryan! I will look into converting the old data. I’ve had to do that before, and while it was messy and complicated, it worked very well. Before I go down that path, I’m curious if it’s possible to implement something like JQuery’s noConflict() function. An ideal scenario is an API that looks kind of like the code in this SO post:
<!-- load jQuery 1.1.3 -->
<script type="text/javascript" src="http://example.com/jquery-1.1.3.js"></script>
<script type="text/javascript">
var jQuery_1_1_3 = $.noConflict(true);
</script>
<!-- load jQuery 1.3.2 -->
<script type="text/javascript" src="http://example.com/jquery-1.3.2.js"></script>
<script type="text/javascript">
var jQuery_1_3_2 = $.noConflict(true);
</script>
I understand that this is a bit of a niche use case, and I am happy to try to implement it in userland.
