问题
I am trying to migrate my project from polymer .5 to polymer 1.0.
I have installed new version of polymer library, iron element & paper element. But I am getting following error:
polymer-micro.html:63 Uncaught TypeError: prototype.registerCallback is not a function
This page does not have any code like:
Polymer('shape-menu',...
Also, I have noticed that directory structure remains same for core elements. It did not changed to iron/ neon elements.
So my code uses the same line to import htmls. Eg:
<link rel="import" href="~/Scripts/Polymer/core-animated-pages/transitions/slide-from-right.html">
Also Please check screen shot attached:

The directory structure maybe same but files present inside are different - refactored/split into multiple files. Since 0.5 and 1.0 are not compatible make sure you update your code too. The change is a big one and it is not simple as just updating your library.
Check their migration guide on changes you would have to make. You may have to change quite a bit. Features that you use could be deprecated, so you will have to use newer alternative. The Polymer authors have created a tool called polyup to assist in migration, so check that out.
