Unless SP2 is integrated into XP Pro, then one cannot
upgrade an existing XP Home w/SP2 installation using
a non-SP2 version of XP Pro. What you need to do is
create a SP2 "slipstreamed" version of XP Pro, then use
the new CD to upgrade over XP Home w/SP2.

You have two options:

1. Uninstall SP2 from XP Home, then upgrade to XP Pro.

or

2. Create a SP2 slipstreamed version of XP Pro (preferred)
and use the new XP Pro w/SP2 to upgrade.

Either one of the following utilities makes slipstreaming
(integrating) SP2 into Windows XP a breeze:

Note: If you have a preinstalled version of Windows XP Home with SP2,
then you cannot uninstall SP2. You'll have to make a XP Pro CD with SP2
slipstreamed in order to upgrade over your existing XP Home installation.

Hi

You will either have to create an SP2 slipstreamed XP Pro CD or revert to XP
Pro SP1, then upgrade again to SP2. To create an SP2 slipstreamed CD:

You can download the SP2 file (266 MBs) from here:

http://www.microsoft.com/downloads/...BE-3B8E-4F30-8245-9E368D3CDB5A&displaylang=en -
or if you have a copy of the SP2 CD, you can copy the xpsp2.exe file from
that CD onto your hard disk/partition and use that:

then follow the directions in the following article to create a slipstreamed
XP CD:
