Convert Theano deep learning codes to Tensorflow

Hi All,
I am trying to migrate Theano codes into Tensorflow. The Theano codes were written by somebody else and the author didn’t use Keras. So, is it possible to convert the Theano codes into Tensorflow? If yes, could you kindly explain me step by step? I have seen some post in this group but I didn’t get a clear idea on that. Thanks in advance.

@AlexJay, I am also facing the same issue. Can you explain me how to achieve the migration of theano into TensorFlow if you have done it.
