that may be, but I was simply pointing out that they have
made much more of an effort to make the 5.1 to 6.5.x upgrade alot more smoother
and reliable. (at least based on the conversations I had and documents I
downloaded from the Portal).
I have always held off the 6.0 upgrade, and even now I am
going to focus on the jump to 6.5.1.
Remember, I have never used 6.0, so I have no real
experience - but one would hope Symantec Support does and have been involved in
many migrations based on customers
requirements.
I
think what Ed is saying is that either way (6.0 or 6.5) you have to make the
transition from the old flat file binary catalog to the new
sybase/EMM.
Therefore, 5.x -> 6.0 or 5.x -> 6.5 is no
difference.
What
you're saying about an easier transition to 6.5 I believe is merely symantec
providing the means to go direct to 6.5 rather than make an intermediate step at
6.0, where no one likely wants to stay.

Hello Ed
I am basing this comment (as you detailed below) on a discussion with
Symantec. that is not to say its right, but I know after the huge cock-ups
there were with 6.x one of their focus points was an easier transition from
5.x to 6.5 or 6.5.1
Of course, alot would depend on the environment, and also the stability
of that environment. I guess one small fault can cause an endless amount of
headaches and quite possible downtime for your NetBackup
environment.
Having Symantec on the end of the phone could be a good thing....
depending on their expertise me thinks.
In regards to the second comment (see below in blue), I did respond to
this in another thread of the same subject line.
Hopefully this is clear.
Thanks, Simon

What are you basing this on? The 6.0 to 6.5 upgrade has been
relatively painless for everybody. It's always been the 5.x to 6.0
upgrade that has been the issue and the steps to do that are in the 5.1 to 6.5
path - you can't avoid the migration by skipping 6.0.
In general, the
uglier the source environment in 5.1, the uglier the migration, and it hasn't
always been the admin's fault (although sometimes it has been). Some
things worked in earlier releases but were never really documented or
supported and NetBackup is not unique in this. The more complex the
product is, the uglier upgrades are going to be since there are too many input
permutations to even consider testing. There are lots of environments
out there where Symantec just says "we didn't know anybody was even doing
*that*" or "we didn't even know you *could* do that".
If the source
environment would have been bugfree since it was installed, it would be
easier, but it wasn't - all releases that I've worked on, going back to 3.4
had some set of bugs that would leave the system in weird and wonderful
states. That makes the upgrade even harder since they can't just trust
that the source system was pristine. It also doesn't help that sometimes
the upgrade processes themselves have bugs.
> maybe careful planning is the
key?
Careful planning is always key but
this alone doesn't guarantee a successful outcome. Part of the planning,
however, should include a fall back plan...
