Offline update standalone winodws7 client

Hi,

I needs to find a solution to update the definition on a Windows 7 machine (A) running Endpoint protection and it cannot direct access the Internet

we have a Symantec Endpoint server (B) in another office, however, the connection between them is unilize the SFTP protocol so it can only copy the definiation from B to A, is this method work and please advise what is the folder path to store the definitiion in B

Thanks
