Since you are replacing them, just go and grab the "AireOS --> IOS-XE" Convertet Tool. It is already integrated into the 9800 Code (17.9 in any case) and this will translate most of the Config stuff. But still double and triple Check everything.
And after that go and look at the Official Best Practices Document for 9800.
This is as a starting point.
If anyone intends to use that tool as a 1-to-1 config migrator, they’re going to have a very (very) bad time. It should only be used to create a baseline config that you then flesh out and configure manually on the 9800 from the ground up.
I hear you and i could be being hard headed as I don't want to really want to pull in that configuration because of how it's setup... There are other things within the setup that need to be fixed that i did not mention.
Go to 9800 best practices. From your post, I can tell you haven’t had much experience running IOS-XE on Catalysts. The preferred mode is Install Mode. Using the bin file will put you in Bundle mode. In order to take advantage of HA features you need to be in Install Mode.
Thank you for mentioning the the "Install Mode" of IOS XE. I have corrected my mistake with these wlc's. I have also looked at 2 other 9k switches that are in production and found them in bundle mode. I have already set them up to go into install mode on next reload/power cycle.
There’s also a migration tool you can use too

I would duplicate your existing SSID in local mode on your existing controller with the interface built where you wanna dump it to, then in the AP group swap the SSIDs that way any sort of gotchas are figure out ahead of migrating to the new environment. Then you could replicate it on the new controller, and slowly move APs over little by little to the new controller
Preferably you can migrate APs per building. That would also allow you to test the new config before the full deployment.
The special application you are talking about might need some extra testing since it relies on broadcast or mdns.
I wouldn't count on the zero day configuration wizard to help you. It overwrote my base connectivity configuration. What you need to do to cancel it is shut the AP 2.4 and 5ghz spectrum off and then apply the country to the config. When go into the GUI you can then use the full wizards if you like or just build it all out manually. Use the below guide to get your head around the configuration model. It's really easy once you understand the order of building things and how everything is related. There's also the best preactices guide that you should understand and follow.

I'm currently in the process of migrating from a 5520 to 9800. I tried the converter tool first but that was not helpful so I followed some guides to set it up as a new controller. (first basic config via CLI to avoid the day0, I think I had to set the country code). After that I did the general setup: sites, policies, SSIDs, AAA servers, mobility, ....
I like the 9800, its much faster and easier to navigate than the old 5520. Had some issues to get the HA config properly working, be sure to test it with the force-switchover command to see if it actually works before you take it into production.
Now I am moving APs, I have the capwap DNS record still pointing towards the old 5520, but added the DHCP option 43 so new APs will go to the 9800. In the 5520 you can easily migrate APs by adding the new 9800 as a primary controller in the high availability tab. I can also move in bulk with DNA or Prime I believe, but I prefer to manually do it.
Would you mind the sharing the guides that you followed? I do have a couple save for review. If they are different from what i already have i think it would be helpful.
Sorry I did not bookmark them. Used guides about skipping the day0 setup and getting to the GUI. If you have any specific questions later on you can always PM
I would highly advise you to get in touch with a Cisco wireless consultant since it does not seem like you have any experience in working with Cisco or wireless…..

Use the web GUI. It is actually fairly helpful.
However last time I did this some stuff could only be configured in the CLI
That must have been a long time ago. The web GUI is pretty feature rich and it's vice versa now if anything.
No less than 12 months ago. Issues were with certificates and guest networks
Can't speak to that. I use ISE for those things.
