Hello friends!
I sit with a colleague and set up a few things after one year.
I found that there is version 6.7 running there, there is a possibility to come to version 6.8?
Are there any stumbling blocks, incompatibilities?
How would the best approach be?
We use the following services:
DNS
DHCP
MySQL
samba
e-mail
SOGo
greetings

I think you have to read the blogpost that was written when NS 6.8 was released:
http://www.nethserver.org/nethserver-6-8-final-released/
It gives you all info needed to upgrade. But if you have applied alle updates from software center, you probably are already running 6.8. It should say so in the Dashboard.
The information on the 6.8 I had already read 
In the dashboard is 6.7 (final), and the software does not update.
Previously, I had the 6.6 installed, the update to 6.7 ran without problems, but it never goes on …
yum clean all --enablerepo=*
yum update
please try and report
