Can you try with the current trunk head (r24296)? I just committed a fix for the C/R functionality in which restarts were getting stuck. This will likely affect the migration functionality, but I have not had an opportunity to test just yet.
Another thing to check is that prelink is turned off on all of your machines. https://upc-bugs.lbl.gov//blcr/doc/html/FAQ.html#prelink Let me know if the problem persists, and I'll dig into a bit more.
