Use the User State Migration tool to move the system settings and files to the new machines.
Copythe files and the Windows Registry to a removable media then copy it onto the new machines.
Answer: C Explanation:
The User State Migration Tool is made specifically for this purpose. Large scale migrations require not only files but system settings to bemoved to new machines and Microsoft created this tool for this purpose.
What is User State Migration Tool (USMT)?
User State Migration Tool (USMT) is used to migrate user files and settings during large deployments of Microsoft Windows XP and MicrosoftWindows Vista operating systems. It captures desktop, and application settings, as well as user accounts and users#39; files, and then migrates them to a new Windows installation. It helps administrators to improve and
simplify migration process. USMT can beused for both side-by-side and wipe-and-load migrations. USMT component
SCANSTATE.EXE is used to collect the files and settings from the source computer and the
LOADSTATE.EXE component is used to restore the user state onto the destination computer.
Answeroption D is incorrect. Moving the Windows registry will not work and could in cause major problems on the new system. This is especially true if the new system has a more modern version of Windows.
