xfer problems between 2.3.15 and 2.4.17

[Ken Murchison]

Hi Gavin,

Have you tried running reconstruct with the -G and/or -R options to see 
if they fix the corruption without having to remove cyrus.index?

Another option is to place a copy of the user's <user>.seen file from 
the 2.3 machine on the 2.4 machine prior to removing cyrus.index and 
reconstructing.  I *think* the server will then upgrade the seen state 
from <user>.seen to cyrus.index.
