We are completing a number of V2V migrations using VMware vCentre Converter Standalone v 5.5.3 build 2183569
The first sync is completed, and on occasion we run the re-sync in order to bring the sync up to date.
The initial sync's were completed last week, and we've ran a resync every couple of days, leading up to the migration this weekend.
On occasion one or two servers will fail to complete the re-sync. So far we have seen this 5 times across 3 different servers out of the 10. We have deleted the clone on the target and started the sync again, the re-sync then does complete.
At present we do not know why the re-sync can seem to fail at random. Obviously if this happens when we are trying to complete the final re-sync on the night we'll have an issue as there won't be enough time to complete a full sync in the outage window.
The error we see in vmware converter is attached;
