We would recommend the use of the User State Migration Tool (USMT) from Microsoft to migrate the users profile. Note: you will need to have version 4 as version 3 does not support windows 7
details on the tool from MS:
Here are some details on setting up this information in LANDesk via the provisioning tool.
(more information here also: http://community.landesk.com/support/message/25826#25826)
The best recommendation we have is to ensure you test the situation comprehensively also before applying it to any key devices.
It should be noted that there is no uprade installation for XP systems (for Windows 7), you will need to install a fresh install or image, therefore the applications will need to be reinstalled, however the migration tool, should move the application settings, depending on your configuration of the tool.
(Note: If you are only doing a few machines then Windows Easy Transfer might be a better option.)
