This is a quick video on how to move users in active directory users and computers using the command line. I use the command dsmove and Windows Server 2008. these features may be used in older versions of Windows Server.
Commands used
dsadd user “cn=Bob Jones, ou=people, dc=my, dc=domain” -upn “Bob Jones” -samid “bjones” -fn “Bob” -ln “Jones” -pwd * -mustchpwd yes
dsmove “cn=Bob Jones, ou=people, dc=my, dc=domain” -newparent “ou=sales, dc=my, dc=domain”
