0x80041b03 in your logs may be due to Index failures? Try setting the RetryAbandonedFailedItems reg key at the target EV server then retry. During a Move indexes are built from scratch at the target. It's only a guess, so bear that in mind ;)
Also, have you seen the 8 SP4 hotfix reference move archive? It may not be related, but worth checking out;
