How to upgrade correctly?

[anak85]

I updated from El Capitan to Sierra without losing anything. Copy everything from EFI Clover Kexts 10.11 to EFI Clover Kexts other. Download and install Sierra from the app store. I do keep a cloned copy of OS X in case something goes wrong.

Yes, if you read the guide that you linked it is quite obvious that it uses Clover.

Use EFI Mounter (google it) to mount the efi parition, Go to EFI-Clover-Kexts and copy all contents from 10.11 folder to other and I suggest you keep only the "other" folder and delete rest of the folders

My folder EFI-Clover-Kexts-10.11 is empty. Even the "other" folder is empty.

When installing I just used kexts that were included in MultiBeast and added one using Kext Beast for sound after sleep. All kexts are in Library-Extensions.

So in that case there is nothing to take care of apart from hitting upgrade in the AppStore?
