This guide describes how to upgrade a Microsoft Microsoft Windows 98-based, or Microsoft Windows Millennium Edition-based client that has user profiles to a Microsoft Windows XP-based client.
The following steps enable the Windows 98 and Windows Millennium Edition (Me) profiles to be retained throughout the process.
Your best method to retain the profiles is to join the domain during the upgrade installation process.
Otherwise, you must use a workaround method to transfer the profile information over to the Windows XP profile.
During the upgrade installation process, at the networking section, the administrator is offered the choice to join a domain or a workgroup.
If you join the domain at this juncture, you ensure that all the existing profiles are migrated successfully to the Windows XP-based installation.
If you did not join the computer to the domain during the upgrade process, you must use the following workaround method:

Join the upgraded computer to the target domain.
All applicable users must log on and log off (which generates a profile).
Copy the appropriate Application Data folder from the Windows 95, Windows 98, and Windows Me profiles to the newly created user profiles.
