Current adviser trying to switch me to a different adviser
Have a frank discussion with your advisor and stress that you really would prefer to stay with him/her.  Then, explore funding opportunities you can apply for together. Be proactive about the situation. The advisor will be excited about the potential for more external (or internal, if available) funding, and the process of writing the application may bring about new lines of research that you then share in common.  At the very least, this will buy you some time, since it sounds like the school will cover you anyway, at least for a while.  Even if the funding doesn't come through, your determination will be clear, and what you lay out in your application may be sufficient to convince your advisor to keep you on.  If he/she is ready to push you off to a different advisor, it may be that he/she does not have sufficient stake in your work.  If you can fix that, the rest may fall into line.
