Yes, deploying 802.11ac is not all about wireless upgrade. It is about your entire infrastructure upgrade to cater the capacity of wifi.

Here is a good presentation if you are looking something for Cisco products

Here are some of my notes on this topic when studying for CCIEW. It may give some guidance as well

Remember that QoS is hardware dependent (what type of switch model etc). Also it is important to configure end to end (including wired & wireless ), otherwise no point. This is a MUST if you deploying voice/video services over wifi.

And it is very important to configure the same 802.1p / DSCP value end to end.
