I have some pvmovse on 1.5TB sections of data with success, I would warn you it takes quite some time. Copying anything at the filesystem level takes longer due to random access, if you want to try that use rsync repeated times to get things right with minimum down time. DD works well for offline systems, but you need to set a large block size. Like ways though before a bit change make sure you have a backup!
