Command conversion from CatOS 8.4 to IOS 15.0SY

Question

Upgrading an old 6509 running CatOS  to a new 6509E running IOS 15.0SY.  The switch is a core switch that does not have any phones plugged into it but does support voip traffic across the enterprise.  The qos on the switch is as follows
#qos
set qos enable
set qos map 1p2q2t tx 1 2 cos 0
set qos map 1p2q2t tx 2 1 cos 2
set qos map 1p2q2t tx 2 1 cos 3
set qos map 1p2q2t tx 2 2 cos 6
set qos wrr 1p2q2t 30 70
set qos txq-ratio 1p2q2t 30 40 30
set qos wred 1p2q2t tx queue 1 40:80 80:100
set qos wred 1p2q2t tx queue 2 70:80 80:100
What type of qos should I use on the new switch to achieve the same functionality as the old switch?
Thanks

Hi
The answer will actually depend on what traffic you want to prioritize and how much you want to prioritize.
Or you have special requirements like limiting the bandwidth or something like that.
I'd say at the initial stage auto qos is the best option and in case you face any issues tweak it accordingly as you go.
