– These Macs can run Big Sur normally, but Wi-Fi cannot work normally. (This type of model is the easiest to run Big Sur perfectly through the patch, currently it is only a Wi-Fi problem.)
You can follow the steps below, this article is mainly for this type of model.
2012 and Early 2013 MacBook Pro
Not officially supported in macOS Catalina, but are fully capable of running both Catalina and large Sur with a Metal-compatible GPU and upgraded Wifi/BT card. Mac can be patched to run macOS Catalina normally, and it may be patched to run macOS Big Sur: – These Macs can currently launch Big Sur, but there is currently no Wifi or graphics acceleration support. This type of model requires additional steps to solve installation problems. Early-2008 or newer Mac Pro, iMac, or MacBook Pro: MacPro3,1
Macmini5,x (systems with AMD Radeon HD 6xxx series GPUs were almost unusable when running Catalina and will be under Big Sur as well.)
MacBook5,2
Xserve3,1*
*Not officially supported in macOS Catalina, but are fully capable of running both Catalina and large Sur with a Metal-compatible GPU and upgraded Wifi/BT card.
Completely unsupported Mac:

Macmini2,1
— The 2007 iMac 7,1 is compatible with Catalina and potentially Big Sur if the CPU is upgraded to a Penryn-based Core 2 Duo, like a T9300.
2006-2008 MacBooks:
MacBook4,1 (as with Mojave and Catalina, we’ll get on our own here, but Big Sur are going to be running on this machine!)

In some models, the wireless network card is already working (Late 2013 iMac, or your 2012/2013 model uses an 802.11ac network card instead of an 802.11n network card).
If the wireless network card cannot work, you need to deal with it as follows:

‘/Volumes/Image Volume/patch-kexts.sh”/Volumes/Macintosh HD’
“/Volumes/Image Volume/patch-kexts.sh” “/Volumes/Macintosh HD”
Then restart to macOS Big Sur, at this time Wi-Fi is already normal. - Installation method: fresh installation using removable media
Tip: U disk can also be replaced by mobile hard disk, especially SSD mobile hard disk, which is faster.

Carbon Copy Cloner requires macOS. CCC will not run on Windows.Mac mini upgrade os.
Apple advises that macOS Mojave will run on the following Macs: Mac models from 2012 or later. Running Big Sur on another macOS on an unsupported Mac may also be considered against Apple's. But I would rather buy a second generation silicon mac to truly take advantage of the new OS features and remain on Catalina (or HS) for everything else. Or just bootcamp your old unsupported mac to windows 10 as the main OS and macOS as secondary to bring out some of its latent potential to 2021. I could not get it to properly install on imac 9,1.
