Ok.
How do you migrate your config.plist settings?
Open the sample.config side by side to your config.plist and then copy the serials you generated plus all custom and recommended settings you made for your board. Then just rename your config.plist to oldconfig.plist in case you want to look at it again. Finally rename sample.plist to config.plist and add it to your EFI folder.
@Sniki has a Gihub proyect for HP computers like yours. You can download his files and use them as reference to build your own EFI. Just remember to follow carefully the instructions of how to update OpenCore in case his Github EFI is an old version.
Is recommended to use a config editor instead of a config configurator. Configurators are good as long you master them and make sure is the correct version for the OpenCore version you are using.
I prefer to use Propertree, PlistEditPro or Xcode.
Xcode download is to big and that is why most people use Propertree or PlistEditPro but Propertree is free and PlistEditPro is not.
The only thing I don't like about Propertree, once you install it to your App folder, is that you can open with a double click the first file but after double clicking on a second file to compare side by side, the second config.plist won't open. So then it is necesarry to click on the top menu bar on File-->Open to be able to open a second file side by side.
I hope the developer of Propertree fix this on the future.
