There is not enough information here for us to be able to answer your question. Please post the output of show version so that we can see how much memory and how much flash the 3660 has. This is essential to be able to say whether the new release is compatible or not. It would also help if you would post the file name of the new image so that we can see exactly what version and feature set it is. If we know those things we should be able to answer your question.
