Well, yes. This is why a heavily customized internal service, such as
can occur for Samba, would ideally be done on a new server environment
rather than upgraded in place. It's a six year difference in release
date, with the change of a lot of the underlying components.

Months? Unless the environment is really complex, I'd only expect a
few days of work. If you've the resources to set up a small test setup
with a few hosts, do that, then bring the configuration over to a new
server. Trying to do it live, on the same server, upgrading in place,
is kind of begging to trip over some fundamental change in Samba or
even in CIFS.

Jobst? Were you using the default samba-3 from CentOS 6, or the
upgraded samba4-4.2 package before the upgrade to CentOS 7, with
samba-4.8 ?
