I have a fairly new PC that i got not too long ago off ebay, and now i am
looking at installing Vista on it. The upgrade advisor said that my pc
was
good to go so i decided to go ahead and get VIsta Home Premium. While
looking to buy a version of vista i noticed that the Upgrade requires a
clean
install when you upgrade from Windows XP Pro SP2, which happens to be what
i
have. What exactly does this mean? I have looked at many of the other
posts
on windowshelp and just cant seem to figure out exactly what you have to
do
when you do a Clean installation of Vista. Can anyone please explain?
Joseph, you have received several responses, all correct, but not really
clear on your question, I think.
This is the scoop. You can use an upgrade version of Vista Home Premium to
install Vista with XP Pro as the qualifying OS, however, it can only do a
custom install (similar to a clean install), not an upgrade in place where
installed programs are retained and data is migrated. In a custom install
programs are not retained and data is not migrated.
To start either install you run the Vista DVD from the XP desktop, but since
you have XP Pro, VHP will not offer the option of doing the upgrade in
place. Only the custom install will be offered. The old XP installation is
wrapped up into the Windows.old folder from which you can retrieve data if
needed, then delete it.
If doing a custom install you can use the Windows Easy Transfer Utility
(WET) on the Vista DVD on the XP installation before doing the upgrade to
backup data and settings (but not programs) to external media, then after
the installation run WET to bring in the data and settings. Applications
will need to be reinstalled from their original media.
See this link for upgrade paths. The green dots mean an upgrade in place is
supported, the yellow means it can only do a custom install.

To go from XP Pro to Vista by means of an upgrade in place will require
either the Business or Ultimate upgrade versions.
Before installing Vista do some research. Check the hardware manufacturer's
web sites including your computer vendor's site if it's an OEM computer for
Vista compatible drivers. Research the software vendors sites for info on
the compatibility of their software in Vista.
Running the Upgrade Advisor is not sufficient. It is only a guide and can
be wrong. If you go the upgrade in place route, first make sure you
uninstall any programs that the UA says could have compatibility problems.
Even if these items aren't mentioned uninstall all AV programs, 3rd party
firewalls, anti-malware apps, Sonic DLA, any CD/DVD burning software such as
from Nero or Roxio, any system level utilities such as 3rd party
defragmenters, partitioning tools and tweaking tools, and any software that
uses drivers.
Use drive imaging software to make an image of the XP installation before
the upgrade and save that to an external drive so it can be restored if the
upgrade doesn't go well.
