[Samba] Samba Installation question

[Guess Logi]

I wan to download samba from samba.org.
 
If I have installed Linux 8.0, do i need to remove smaba stuff ( pkg, other files ) before i insall new version from web ?. I heard Linux does come with samba by default.
 
OR 

Is it okay to just install new version even though we have older version which came with Linux ?
 
Any input would be appreciated.
