I really wonder why the so called personal backups, or settings backup, exists: I've never ever had the chance of using it at every change of version.
The question is: if they cannot be used for a new version why do they exist? Because, frankly, I find useless them for the same version.
If I do a fresh install of the same version I have, is because I want to know if a problem depends on some plugins or customization.
So, if the fresh install solves the problem, I surely don't want to "contaminate" it by the personal backup.
On the contrary, if the fresh install has the same problem of the "complete" install, I simply go back to it by a full backup.
So, the personal backup is completely useless within the same version. But it's never possible to take advantage of it upgrading to a new one.
All the "normal" settings, I mean channels, are too easy to save even without this kind of backup.
So, even this time, I installed everything from scratch and then I had to re-configure tuners, plugins, NAS and mounts one by one...
