Oh yeah, I heartily agree. In-place upgrades are a brand new feature of RH7 and notoriously complex for any Linux distribution. I've done in-place upgrades of Ubuntu and Debian - and the list of possible problems and bugs in the upgrade process is always long. Unless it there were a very compelling business reasons (e.g. a very small business without budget to get new hardware and major need to get on the new distro), I'd avoid doing the in-place upgrade to RH7.
I've always viewed the main use case of in-place upgrades as people running the distro on their laptops/desktops. That's the one situation where I'd consider the pain of an in-place upgrade. Installing all my programs and migrating all my data to a new laptop can be a big nuisance too - maybe outweighing the pain of resolving all the issues with an in-place-upgrade.
But of course, if I was about to buy myself a new laptop anyway then I'd definitely switch to the new distro at the same time and avoid the upgrade.
