updating a pair of samba 4 AD DC

[David Mansfield]

Hi All:

I have a pair of samba AD DC for our single domain which are running, 
4.0.1 and 4.0.5. There are quite a few issues with these servers which 
I'm sure you all can imagine, given the vintage.

The issue is that for a long time the "samba-tool dbcheck" was in flux 
and I was never sure exactly what the recommended procedure was.

So now I'd like to upgrade them to 4.2 next week (or so).

Here's my approach:

- shut down 4.0.1 server. update sw. restart
- shut down 4.0.5 server. update sw. restart
- shut down former 4.0.1 server
- run "dbcheck" etc. on the remaining running server
- restart both servers sequentially

Does this seem correct?

In general, what is the sw update path when more than one server is 
running in a domain?
