Re: [Veritas-bu] Lets hear about your upgrade experience! 5.x - 6.5

I don't know that upgrading to 6.5 is
any easier than going to 6.0. Granted there are some known issues in 6.0,
but I think that's beside the point of this discussion. The main reason
it's easier is because Symantec realized they dropped the ball after there
were a high number of people having upgrade issues when going to 6.0. After
that, they got it together and put out the documentation set. While the
docs are much better than nothing, I still think they could have done a
better job organizing the steps as some steps overlap and others contradict
previous information.
With that said, I have upgraded two
environments to 6.5.0 from 5.1MP6 successfully. I owe this success to the
docs and taking the time to following the steps (though as said, that's
not a guarantee all will be well). The first upgrade ran into some minor
snags, the second went well, and I have another one scheduled for next
Wednesday. Here's hoping I didn't just jinx myself!

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...
