How will transfer data stored on hdd between yur old pc and new one using lan cable ?

Assuming that you do not have a network, Use Cross-Over Cable to connect two PC's & copy data from one computer to another.

In fact I am not expertised in IT but I think it is possible if u have google drive or any other such as drop box. I am specialized in Chemistry. If u have any question related with my specilation u r welcome!
