Deployment with AirEngine 9700 Basic concepts

Hello friends.

I hope everyone is very well, I come to you seeking your help with the following concerns.

I am trying to understand how AC Huawei works, I have always worked with another brand and now I have a project where I have to implement a Wireless network with a pair of AirEngine 9700 Series equipment.

Some of my initial questions are as follows:

There is documentation that they recommend me to deal with the topics of:

Initial configuration of ACs

• AP registration process

• APs and ACs update process
  

• WLANs configuration process and configuration parameters.
  

• Registration process of association of APs with CAs  

    2. With another provider, the software version of the controllers is shared with the APs, I do not understand if in the Huawei ACs the process is the same, or if the software versions of the AP must be uploaded to the Acs independently so that it works as a repository.

    3. How can I check the compatibility of versions between ACs and APs.

    4. Where should I configure DHCP for my APs and my clients, on ACs or a Switch or Router.

    5. Any additional recommendations that you can give me.

Thank you in advance
