s_shivaraj,

After copying you can add the following step to release all the unused space.

Code:

//STEP0100 EXEC PGM=IEBGENER                         
//SYSPRINT DD  SYSOUT=*                             
//SYSUT1   DD  DUMMY,                               
//             DCB=(LRECL=nnn,RECFM=AA,BLKSIZE=0)     
//SYSUT2   DD  DSN=YOUR SEQ FILE,
//             DISP=(MOD,KEEP,KEEP),                 
//             SPACE=(TRK,(1,0),RLSE)               
//SYSIN    DD  DUMMY                                 
//*                 


Hope this helps...

Cheers

Kolusu
