 Moving from SUP720 GE interface to WS-X6724-SFP? There is slight 
difference in how they handle QoS but nothing major. Also WS-X6724-SFP
has 'only' single 20G channel to the fabric so overbooking is possible.
 Naturally you can't 'preconfigure' the subinterfaces in WS-X6724-SFP
if you intend to use same VLANs, other than that, can't think
of any issues.
