Use robocopy; I've used it without any problems for several migrations. If you're expecting problems, just set /r (retry) and /w (wait) to something like /r:1 /w:1.
Some other hints:
- robocopy will *by* *default* only copy files that aren't in the target already.
- If you want to do several sync runs, you can use /mir to delete files in the target that aren't in the source anymore.
- use /copyall to copy NTFS permissions as well.
- Check robocopy.doc in the ResKit installation folder (to run it, you actually only need robocopy.exe), it's a very useful documentation.
- You can safely use /nfl (no file list) and /ndl (no directory list) to reduce the log file size; errors will still be logged.
- Use /np if you're logging to a text file, otherwise the log will be filled with control characters.
- Since W2k8, robocopy is already included (but without robocopy.doc).

That's what you configure with the /r (retry) and /w (wait) arguments: how robocopy robocopy should react when it encounters files it can't copy, that is, how often it should retry the copy and how long it should wait between retries. In your case, these need to be low (default is 1000000 retries and 30 seconds pause, which would effectively stop the copy at the first file that can't be copied).
