Problems with IMAP XFER 3.0.4->3.0.4 server

I'm in the process of moving dead but currently not to-be-deleted users off a  Cyrus 2.5.8 server to two new 3.0.4 servers.
I use the XFER command. It works fine from the 2.5.8 server to the 3.0.4 servers but I can't move between the 3.0.4 servers or back to the 2.5.8 server.
I've debugged  the imapd processs and it seems that the problem is that mailbox lookup returns empty and nothing consequently is done

I.e (details masked)

#  telnet server-258 143
00 login cyrus SNIP
00 xfer user/xyzzy  server-304-a
00 OK Completed

The user was actually moved

# telnet  server-304-a
00 login cyrus SNIP
0 xfer user/xyzzy  server-304-b
0 OK Completed

Nothing happened.

I've used quite a lot of time on  the problem and could need some help.. : -)

Included below is  the config for the two 3.0.4 servers-

The logs are not of much help.
