[Samba] Upgrading Samba in a Multi DC environment

[Chris Alavoine]

Hi Marc/Ricky,

Many thanks for the advice.

I am running samba-tool dbcheck --cross-ncs at the moment but it seems to
be taking a very long time, is that normal? It's been running for about an
hour now and hasn't outputted anything as yet.
