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?
