Rename a module in erpnext

I have created a module. this module have several doc type linked with it . Now I want to change the name of the module. Is there any specific way to do so?? Please suggest me .

Since the module name is the folder name too you will have to move all the doctype controllers (JS & PY) to the new module

Is it possible to rename a module without creating a new module ?
I just want to rename the module name .
