Check this thread
Thanks In Advance
Please upgrade directly to 7.5.04 as it has fixed lot of issues. You can directly upgrade 6.x to 7504.
Here are all the links that you need.
Upgrade portal link http://www.symantec.com/docs/TECH74584
Upgrade steps are listed in NBU 7.5 Installation Guides.
Below link will provide all the docs on 7.5
Take a look at my solution in this thread - hopefully makes the process simple for you:
Just check the pre-requisites first - when you open the browser.exe to do the installation their is an environment check that you can run to make sure you are OK - run this ahead of time and it will advise you of anything that you are missing
The above relates to Windows so hope it helps
