We have 3 NW servers, with one NW server being a live "test" box.  It has only 
9 clients, so that is the backup server we upgrade first, to test new software. 
  That server is also our NMC  server.   A couple of weeks ago, we upgraded the 
NMC server to 8.0.1.4, and had mixed results.   Our main production backup 
server, never missed a beat. It is running 7.6.2.1.7, and hasn't had one 
problem, even with the NMC on 8.0. 

However, our other box had all kinds of issues, as somewhere along the line, 
nsrauth, had been removed from that's server's configuration.    NW 8.0 
requires nsrauth, not oldauth, so this server, also running 7.6.2.7, would not 
communicate with the NMC 8.0 box.     Once we got that straight, renamed tmp 
and nsrd directory, and rebooted, we were able to get everything working 
properly. 

We've now been running a mixed environment for about 2 weeks, and will upgrade 
our 2nd server to 8.0.1.5 later this month.   If there are going to be 
problems, it will most likely be on this upgrade, as this NW server has 
multiple storage nodes, and several hundred clients attached to it.

I've spent all this week migrating my NW server to new hardware (that was 
Tue), and the last 3 days replacing/upgrading hardware and VMware patches. 
Haven't had time to look at the NW notes yet. But I've done upgrades from 
7.2 through each version up to 7.6, so I was hoping that the process 
hadn't changed a whole lot with 8. Yes, I will read the notes before I 
actually do it (next weekend), but I was hoping I remembered the change in 
ordering correctly.

Hmmm. Not sure that will help me. Unless things have radically changed, a 
restart isn't required when uninstalling 7.6.2 and installing 8, on a 
Windows storage node. But even so, I can only do that on scheduled 
downtime (just in case), which is next weekend. And with Windows, it never 
really hurts to restart, required or not ...

I will keep an eye out.
