Hi Arul,
If your production environment is currently empty and just waiting to be filled with the same content from the DEV environment, then a "copy data source" option as suggested by Nikhil would work best.
The "Copy data source" tool would copy over your cms tables. And the filestore can be brought over manually.
And as already asked above, any particular reason to not go with Import Wizard (3.1's mass migration tool) or LCM (3.1's batch migration tool)?

Siddhartha
