I would like to automate my upgrade from W2K to XP Pro on client PCs. I have created an unattend.txt file to go along with my batch file set to run upon boot, pointing to the unattend.txt file. I can only find a reference to "UpgradeWin9x=Yes" to upgrade from 98, no reference to a upgrade from W2K entry in my unattend.txt file. I tried UpgradeWin2000=Yes and this didnt work. If anyone has done this before please point me in the right direction. TIA!
