Moving datafile will not remove it from SYSTEM tablespace. You can not reassign datafile from one tablespace to another. Now I'm not sure, what are trying to do? Did you find may be "user" objects in SYSTEM tablespace? Then, it's totally different story.

  Well, I have recieved a server and found some datafiles   are reside in System tablespace - in this case to move   those datafile we can not put system tablespace offline   therefore can not use alter command...

    using alter database rename file you can just take the tablespace that     owns that datafile offline and do the work. All users who don't need     that particular tablespace are not affected.
