You should be able to do something like this in your transports 
file during your migration:

knownuser1 at     lmtp:unix:/var/run/cyrus/socket/lmtp
knownuser2 at     lmtp:unix:/var/run/cyrus/socket/lmtp
knownuser3 at     lmtp:unix:/var/run/cyrus/socket/lmtp                smtp:[]

see the man page for postfix's 'transport' for more details.

You might also be able to make use of an ldap 
mailbox_transport_map to do the same thing:
