[Veritas-bu] Upgrade Scenarios (SW+HW). Will it work?

Kat
The first option is not valid. You can not recover 3.4 catalog to the
server with 4.5 installed. It may work, but it is unsupported and can
cause various problems.
So you have two equal options:
1) Perform the upgrade to 4.5  on the old server, install 4.5 on the new
server and run bprecover
2) Install 3.4 on the new server, run bprecover and after that upgrade
the new server to 4.5.

Be aware that in addition to file covered by bprecover, netbackup stores
some optional configuration  parameters in vm.conf file and in the
windows registry:(  In case you have such parameters , you need transfer
this stuff to the new server in addition to performing catalog
restoration.

Hi all,

Further to my previous unanswered question I am now thinking of the
possible scenarios to upgrade. I will change the Master Server PC as
well as upgrading from 3.4.1 to 4.5 (Win2000 still applies).

So, I really need to consider how upgrade will be performed. So far I
have two scenarios:

1) Install NB 4.5 to the new PC and then perform a catalog restore from
3.4 (supposing I took a catalog backup from 3.4 first).
    Do a cat_convert to convert the catalog to binary format.
   Hope everything works

2) Install NB3.4.1 to the new PC and then perform a catalog restore from
the 'old' 3.4.
    Upgrade to NB4.5
    Do a cat_convert to convert the catalog.
    Hope everything works...

Since some of you have already been through this, can someone share his
wisdom? Are there any complications to be aware of?


I performed a test upgrade (scenario #2 ), but using a standalone tape
drive instead of a robotic one. Everything seemed ok (well, except for
the catalog restore, since there was no robotic devices on the test
machine....) and I encountered no problems.

I wish everything run smoothly when I perform the REAL upgrade.


Thank you in advance

Kat
