Migration from exchange 2003 to exchange 2010 - local or remote move option

Hi
I have migrated all user mailboxes to my new exchange 2010, all successful mailboxes show as Usermailbox.  A couple of users still showing as 'Legacy mailbox'.
I tried right click over them and there is no option to move local or remote move.  Even the ones which have been successfully migrated have no option of local move.  I need to move all users and have the option of local or remote move under EMC.
Help plz
