The Migration Aftermath
If any of your transferred programs don't work properly under Windows 7, you can configure them to run under virtualized XP via the Program Switcher.

When the PDUW7 upgrade wizard finishes, Sayid's videos return with a brief (but helpful for Windows 7 neophytes) tour of the new Windows 7 landscape, as well as a primer on how the Parallels Desktop virtualization software works.
A close examination of our post-upgrade test system indicated that the migration was a success. Data files from the original XP installation were located in their appropriate folders (including the myriad files and folders residing on the cluttered desktop) in Windows 7, and all programs were present and accounted for in the Start menu.
At least one of the programs installed on our test system, Quickbooks 2005, proved incompatible with Windows 7, and thus required the Parallels Desktop virtual XP environment to function. Aside from an initial delay when launching QuickBooks, there was little indication of the program's virtual underpinnings.
Programs set to run in the virtual environment still appear in the Windows 7 Start menu, and thanks to Parallels "coherence view," virtualized applications appear as if they are running natively (i.e. not within a separate XP window). PDUW7 was smart enough not to migrate to XP apps that would be inherently incompatible with Windows 7, such as anti-virus utilities.
PDUW7 consults its own software database to determine which programs will automatically get the virtual treatment, but if a program unexpectedly has problems running natively under Windows 7, the Parallels Program Switcher lets you relegate it to the virtual environment with a few clicks. You're also free to run your entire previous XP environment (as it existed at the time of the upgrade) at any time you like.
An important caveat: when using PDUW7 to upgrade an existing system, be sure to take heed of the program's disk space requirements, because while it requires an amount of free space equal to the size of your Program Files folder plus 25 GB, it doesn't actually do an advance disk check to verify the necessary space is actually available.
As a result, our initial attempt at an in-place upgrade went down in flames with an error message toward the end of the process as the system's smallish hard drive (which happened to be just over 50 percent full) ran out of space -- turns out we were just short of the threshold. Luckily, our backup saved the day, allowing us to restore the system and successfully repeat the upgrade after removing some junk.
Disk space isn't likely to be a problem when doing a transfer upgrade involving an external hard disk and new Windows 7 PC with storage capacity greater than the original system, and we didn't have any problems when doing such upgrades.
Your License, Please
Finally, let's get back to the matter of licensing. The deal in a nutshell is that Microsoft's operating system licenses frequently place restrictions on how the product can be used, and most prohibit you from moving an OS from one system to another or running it in a virtual machine simultaneously with another copy of Windows. The problem, as it relates to PDUW7 and your original copy of XP, is that you may very well be doing the former, and you'll certainly be doing the latter.
Parallels' position is that PDUW7 users are responsible for remaining in compliance with software licensing -- a disclaimer to that effect is appears at the start of the upgrade process. Fair enough, but figuring out what your OS license does or doesn't allow is easier said than done (it often comes down to reading and trying to interpret the legalese contained in your EULA).
All we can tell you is that if your organization has corporate volume licensing for XP -- generally the least restrictive -- you may be in the clear, but OEM licenses (i.e. XP was pre-installed by the computer manufacturer), preclude continuing to use XP following a PDUW7 upgrade. Retail licenses (i.e. OS in a shrink-wrapped box) are more of a grey area. (If you're not sure of your status, you can try contacting Microsoft by phone or chat.)
The Bottom Line
There's no question that the capabilities of Parallels Desktop Upgrade for Windows 7 are head and shoulders beyond the transition tools that come "in the box" with Windows 7. For example, Microsoft's own Windows Easy Transfer program can move files and OS settings but not programs, and while Windows 7 Professional includes XP Mode for running older, incompatible programs in a virtual environment, you still need to reinstall those programs yourself, and you'll often need to install XP Mode too. (That said XP Mode has the considerable advantage of automatically including a license for your XP environment.)
Potential licensing headaches aside, if you're looking for the quickest and smoothest path from XP to Windows 7, Parallels Desktop Upgrade for Windows 7 is the one to take.
Price: $39.99, or $49.99 with a specialized USB transfer cable; businesses can get a modest 10 percent discount when purchasing 10 or more licenses. Call 425-282-6448 for a quote.
Pros: Automatically transfers files, settings and programs from XP to Windows 7; runs apps in virtualized XP environment for compatibility if needed
Cons: Microsoft's licensing rules may preclude you from continuing to use XP post-upgrade; doesn't check for sufficient disk space when upgrading an existing system
