In most of the cases it is enough just to copy an existing license file from an old database and paste it to the new one.
Old Audi database license file to copy to the new Audi database folder.
Old BMW database license file to copy to the new BMW database folder.
And so on.
If this doesn’t work for you, you will need to use an activator and run full activation process with new database.
