Dojo toolkit application with Dojo2

Hello All,

I have given task to explore migrating Dojo toolkit(old) application to Dojo2(new), They were suggesting that instead of re-writing all dojo toolkit modules can we use the same inside Dojo2. I gone through Dojo2 basics and got to know that we can use Dojo2 with existing dojo toolkit (like webcomponents) , but not sure of using dojotoolkit inside Dojo2. Do anyone has any insights on this. Just looking for a path, even a Yes or No answer would be much appreciated.
