Go to http://www.feedly.com/home#index and run this. It'll tell you how many feeds you have on feedburner. Now I just need to automate unsubscribing these and subscribing the original urls.

gistfile1.js

var burners = [];
var feedEls = document.querySelectorAll('#feedlyPage > div > div.cell > div');
Array.prototype.forEach.call(feedEls, function(val){
    var feedUrl = val.getAttribute('data-uri').replace(/^subscription\/feed\//g, '');
    //console.log(feedUrl)
    if(/\.feedburner/g.test(feedUrl) || /\.feedproxy/g.test(feedUrl)){
      burners.push(feedUrl)
    }
});
console.log(feedEls.length, burners.length)
