All the samba servers are internal servers unreachable from the outside, so loosing the updates of the OS was my least concern.

Ah, I think you are mixing up 'minor' with 'revision'. Samba uses 
'major.minor.revision' , the latest version is 4.10.4. If something 
dramatic changes, then the 'major' version will change, this last 
happened when the ability to provision an AD domain was released i.e 
Samba went from '3.x.x' to '4.x.x'. If minor changes are made, then the 
minor version will change, these changes could be the addition or 
removal of smb.conf options, though removal will mean the deprecation of 
the option at a minor release before being removed at the next minor 
release. The 'revision' releases are for bugfixes and/or security 
problems, nothing major should be changed.

This all means that before you upgrade Samba, you should read the 
release notes for the 'minor' releases, there have been a lot of changes 
between the Samba that Centos 6 used and the one that Centos 7 uses.
