Hello.

Are you saying your system doesn't use shadow passwords?

You should not replace the files, you should only copy the content of the file that you are interested to replicate, and ensure that you don't have any duplicate UIDs.

If you are sure, and you want to replace the files, you should copy passwd, shadow and group files.

Hi Rohit,
My question woud be why you want to such a thing.
If you are tring to achive single login to both systems you could have implemented public/private key auth via ssh.
Any way as above post said never over write these files because it will over ride the permission aswell.
Over write contain would be the best and safe way.
Yes, you need passwd group and related shadow files to make things working.

Good Luck...!
