It's weird. We did another test conversion and found no differences in  
the redirection table. It must have been something we did post upgrade  
but we're not sure what.
We did turn on UID links after the last upgrade where it wasn't turned  
on before. We'll continue to explore that as a source of the issue.
Thanks for your help.
