Clonezilla does the migration job quite well. 

If the target disk/partition is bigger than the old from where you are 
copying the data, you can adjust some options when restoring the cloned 
image to avoid missing hard disk space.

I'm not sure in what stage of the migration are you right now (I did not 
follow the full thread), but have you tried to boot from a LiveCD and 
work from there?

If this neither works, I guess you can safely re-format the target drive 
and start from scratch (make a copy first if there is valuable data you 
can save).
