Update from Clover to OpenCore on Catalina. And upgrade from Catalina to Big Sur
So I decided to upgrade to Big Sur, and Clover are not good to go with. So my steps was:
1. Update Clover and kext
2. Update macOS to latest Catalina
3. Create boot USB with OpenCore bootloader
4. Test that I'm able to run system from USB OC boot, and all hardware working as before
5. Change EFI to OC
6. Update to Big Sur
CPU: Intel Core i5-9600K Coffee Lake 6-Core 3.7 GHz
GPU: Sapphire 11265-05-20G Radeon PULSE RX 580 8GB
RAM: 2x G.SKILL Aegis 16GB 288-Pin DDR4 SDRAM DDR4 2666
Motherboard: ASUS Prime Z390-P (Chipset Intel Z390)
Audio Codec: Realtek ALC887
Ethernet Card: Realtek RTL8111H
Wifi/BT Card: Broadcom BCM943602CS (**PCI-E**)
SSD: Crucial MX500 500GB
BIOS revision: 2808
In my build everything works well on Clover/Catalina, so I update Clover and kext and download Big Sur through AppStore. It's firs time I ever touch OC, but guide on their site is simply amazing, and I just follow every steps and carefully read every instruction.
[https://dortania.github.io/OpenCore-Install-Guide/](https://dortania.github.io/OpenCore-Install-Guide/)
By the guide I made USB Installer, just follow all instruction for Coffee Lake for config.plist, and pay attention to comments about Z390 chipset. I didn't add anything else, but whats on guide. For now I use debug version for kext and OC.

I have more SSD with Windows and for backups, so I disconnect all and leave only macOS SSD. And try my boot usb, to run installed Catalina through OpenCore. And you need to see my happy face, when everything boot same as with Clover, its mean we good to go and replace Clover with OpenCore.(I was so happy, cuz when I make my Clover install first time, it took me 6 days to simply run macOS. But that time I was newbie)
So I replace EFI, reboot, check that everything works well. I decided to log out from all iServices and clean mess after Clover, there is guide for that. So later I will create new serial number for iCloud.
Next step, simply open Install macOS Big Sur from Applications, and click update. There will be some 3 or 4 reboot during the update.
And Big Sur hackintosh is ready!

Follow after install guide, create new serial, change debug OC and kexts to release versions, add GUI to OC. Only one think happened after install, is BIOS on every reboot posted in safe mode, so I add AppleRTC kernel patch and it fixed the issue.
No magic for Wi-FI/BT: airdrop, copy/paste from iPhone works from the box. I use Aliexpress WI-FI card, but expensive one for 60$.
Huge Thanks and respect for OpenCore team! They did really huge and impressive work.
Sorry for my English, hope it all have sense.
