Copy ABAP Programs from one SID to Different SID

Hi Gurus,

As i did client copy,now i want to copy all programs from one SID to Another SID.As i have searched on sdn i got same

questions raised,but it will be a lenghty process.As i have so many programs,so it'll be a tough job to download all programs and

upload them one by one.So kindly tell me the easiest way to download these programs at once.

Thanks & Regards
