Question about upgrade installation.

[roraniel]

I am doing an upgrade installation for friend from Vista Home Premium to Windows 7 Ultimate. I normally like to do clean installs but the friend doesn't have installation CD's for their numerous applications.

I have done a disk image already for backup but my question is, should I make sure Vista is completely up to date with all the current patches before the upgrade install or doesn't it matter? Right now it is at SP1. Also, I assume I should turn off any AV programs before I start?

I don't think it is necessary to install all the updates. But you have to disable the AV.

Upgrading from, say SP1 to SP2, may require a patch to be installed; but installing from Vista to W7 - Vista need not be updated. No need to de-activate your AV too...

I think you've taken wise precautions, however if you just follow the above then you should be alright.

i didnt know that you needn't disable AV. Then woudnt it interfere with the upgrade?

Everything went smooth.

The compatibility check flagged Avast AV, iTunes, and HP Quick Launch Buttons Software. I uninstalled these programs and the upgrade completed without any issues, but unlike a fresh install it took about an hour and a half to complete.

After completion I did Windows Update, reinstalled the latest versions of the apps I uninstalled, did a disk cleanup, did a disk defrag, and the laptop runs better than new according to the owner.

you may need to disable / uninstall AV to avoid any capability issues during installation. I suggest to use Windows 7 Upgrade Adivisior before you go for windows 7.
