Jason, et al-

An upgrade from 3.1.1 directly to 3.4 IS supported.  see p.21 of the 
NBU 3.4 install guide 
(http://seer.support.veritas.com/docs/232352.htm) or technote 232654. 
(http://seer.support.veritas.com/docs/232654.htm)  (and I've done it 
myself a time or two...)

BUT, Hamid said he is upgrading from 3.1 as opposed to 3.1.1.  On the 
one hand, I *think* that the difference between 3.1 and 3.1.1 was 
just a fix for Y2K compatibility, so maybe upgrading from 3.1 --> 3.4 
might work fine too.  But that upgrade path is definitely NOT 
officially supported without unless the first step is an upgrade to 
3.1.1 or 3.2.  (and I could be wrong about the small difference 
between 3.1 and 3.1.1 - we're talking about 5 years ago and I'm 
getting old...)

When it comes to the NBU client binaries, the 3.1.1 --> 3.4 upgrade 
is not only supported, it's trivial!  This is really no different 
from the last step of the NBU patching process - the "update_clients" 
script gets run on the master server, and it does a practically-blind 
overwrite of the client binaries.

And I certainly concur that any extensions (components) need to be 
kept in sync with the rest of the NBU install - there's no way you 
should expect the 3.1.x NBU Oracle extension to function properly if 
it's running on an NBU 3.4 client.
