Eeek! My thread, for some reason or the other, has vanished! Maybe it was accidentally deleted when the mods were battling a shower of disgusting spam with which some *insert four-letter word here* was flooding the Norton community this afternoon (afternoon in Swiss time). Luckily...I have printed out the instructions which have been posted so far. I am posting them again:
My computer specs: Sony-Vaio laptop running on Windows Vista Home Premium SP1, about 11 months old; security software: Windows Defender and NIS 2007. The question concerned how to update to NIS 2009 without anything going wrong (because of needing to delete NIS 2007 beforehand).
Summary: one method which was immediately excluded was to install NIS 2009 over NIS 2007, i.e. letting NIS 2009 remove NIS 2007. Not clean enough. Too risky.
Preferred method:
remove NIS 2007 using the removal tool (IF THERE IS NO OTHER NORTON PRODUCT ON THE COMPUTER. THE TOOL REMOVES EVERY SCRAP OF NORTON ON THE COMPUTER)
1) First, save NIS 2007 product key to notepad and/or print it out. It will be needed to activate NIS 2009 later on; also, write down Norton account user information (username and password)
2) Download NIS 2009 installer (package of about 64 MB) from...alas, the link got lost with my deleted thread! Sigh.
3) Download Norton removal tool from...lost that link, too.
4) Create manual system restore point (my suggestion)
5) Disconnect from internet (my suggestion)
6) Deactivate Windows Defender and any other security software. Leave NIS on, however. The tool will unload it automatically during the deinstallation process
7) Run removal tool once. Reboot (this step should follow automatically)
8) Install NIS 2009 (said to take less than 1 minute)
9) Activate NIS 2009 with product key and run LiveUpdate
The only thing I'd need are the missing links for the Norton removal tool (for Windows Vista) and NIS 2009 installer package (for Windows Vista).
Thanks and credit for the information and instructions go to (scrambles around the printouts):

I am too exhausted to do any deinstallations and installations now. The Windows Defender false positive gave me a rather sleepless night, and today, the public transport broke down when I was coming home from Uni, I had to walk a lot of the way home...in high heels on a wet and uneven ground...*sweat*.
