xfer problems between 2.3.15 and 2.4.17

[gavin.gray at ed.ac.uk]

So I'm going to attach the cyrus metadata files for a folder that behaved 
the way I am describing having been xfer'd between 2.3.15 and 2.4.17.

these are the files from the source server ie the 2.3.15 backend.

If anyone with far deeper knowledge of cyrus than we do, could have a look 
to see if they can identify a problem and possibly find a solution then we 
would be very grateful.
