Unfortunately so far we couldn't reproduce the issue. We really tried it at 
the last PIM meeting and I will give a try once more as soon as I have time.

Currently I'd suggest that way. Just ignore the migration and create the 
accounts again.

I am strongly suggest against using SQLite for Akonadi. My number of gray 
hair grew until I realized that my distro patched Akonadi to default to 
SQLite. There is no migration path between database backends, so your only 
solution is to change the backend and import everything again. What you will 
loose is meta information stored in the cache ("real" data will not be 
lost). If you already had KMail2 set up and used filters to move mail 
around, you'll have to reconfigure the filters (basically the destination of 
moves).

I can't comment how MySql performs on NFS. 

I hope we will find the cause of data loss soon. There were already fixes in 
maildir and mixed maildir resources, one fixed a data loss when downloading 
POP3 mails, but as I said so far we couldn't reproduce the copy/move data 
loss between folders.
