[CentOS] Transferring user quotas?

Is there a way of transferring user quotas from one machine to another? 
Where does the quota get stored? Non of the scarce documentation for the 
quota commands tells this. Apparently it can't be in the aquota.* files 
since I can repquota without them. Or does it get saved in some humanly 
unreadable filesystem information?
