Is it easy to migrate softwares from XP to WINDOWS 7 and what is the procedure?
will it effect on the performance
FYI - check the blogs/forums...

Many people ask about migrating from Windows XP to Windows 7, so I thought I would share an excerpt from the Engineering Windows 7 blog:

There's no change here to the plan as has been discussed on many forums.  We REALIZED at the start of this project that the “upgrade” from XP would not be an experience we think would yield the best results. There are simply too many changes in how PCs have been configured (applets, hardware support, driver model, etc.) that having all of that support carry forth to Windows 7 would not be nearly as high quality as a clean install. This is something many of you know and already practice. We do provide support for moving FILES and settings and will prompt at setup time, but applications will need to be reinstalled. We know that for a set of customers this tradeoff seems less than perfect, but we think the upfront time is well worth it.

If you have any questions about the specifics of performing a clean install (also known as a CUSTOM install) or migrating user settings, please ask your questions in a new thread in this forum.

Sincerely,

No upgrade path from XP to 7...
You could try the FAST ( files and settings transfer wizard ) but don't take this as a recommendation.Honestly, I'd just do a clean install. There's no upgrade path from Xp to 7.
