kdepim-4.7.2-kmail-migration.patch
This version of the patch disables only this migration permanently and not future ones (with new target versions.)
That said, I'm not convinced that that hunk is correct in the first place. Does a user really expect a "no" to be permanent? I'd expect it to be a "Not now", not a "Never".
