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:

How to remove Windows XP Service Pack 2 from your computer

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.

:
| I have installed WinXP Home Sp2 and am attempting to upgrade to WinXP Pro SP1
| for files permission capability. The installation program states that I have
| a newer version already installed and will not proceed.
| If I remove SP2 (according to Tech Support), then the install will proceed,
| but that I will have to reinstall the 30 programs that were installed after
| SP2 was installed. Is there not a work around here? Thanks
