I have an old laptop that came with XP Home gold preinstalled. At the
time, I purchased an XP Pro retail upgrade, which included SP1, and
upgraded the laptop.
I'm replacing that old laptop with a new one (and totally decomissioning
the old machine), which also has XP Home preinstalled, but this time with
SP2 and some post-SP2 hotfixes in place. I want to upgrade the new laptop
to XP Pro. I want to slipstream SP2 and the post-SP2 hotfixes into the XP
Pro upgrade+SP1 files and create a new CD.
If I successfully slipstream SP2, et cetera, will I be able to correctly
upgrade the new laptop in-place? I've installed from scratch with
slipstreamed media before, but never upgraded. I would expect that as long
as the upgrade disk has a superset of the service pack(s) and hotfixes
prsently installed, the upgrade should work correctly, no?
