Could you please provide any source of this recommendation? I am not aware of anything like that.
And even if it was true, it would be nonsense. Who would ever develop upgrade process like this? It's developers' task to think about such cases and make sure thing will work out.
I am still waiting for OS v7 which will handle my snapshots properly.
I have more snapshots. Whenever i like my tweaking, I just take snapshot. And I have many of them. Will I need them in the future? I don't know. Why on earth should I save them as rigs if I am not sure I like them?
Didn't CK say that 'guitarists should not lost any amp settings' - that's why Snapshots were introduced?
