MLS QoS configuration into C9300

I have to migrate  the configuration of a Catalyst WS-C3750G-48TS  to a Catalyst C9300-48T.

 

I could pass most of the configurations of the old Switch to the new one. But there are mls qos commands that are not supported anymore for the C9300.

 

Into the global configuration of the 3750, there are configured the following commands:

 

mls qos map cos-dscp 0 8 16 26 32 46 48 56

mls qos map ip-prec-dscp 0 8 16 24 32 46 48 56

mls qos

 

And all the interfaces of the switch are configured with the following commands:

 

mls qos trust dscp

priority-queue out

 

 

I want to know the EXACT  equivalents of all these commands for the C9300. I was reading the following guide to migrate mls to mqc, but it doesn't describe the exact configuration for the commands "mls qos map cos-dscp" and "mls qos map ip-prec-dscp"

Most of these commands have changed in the newer platforms and IOS versions.

Here is a document on qos for the 9300 series.
