The update table referred to in the Wiki says you can downgrade from .27, .28, or .29 by installing 2.12/1.02.20 in one hit, and yet only upgrade from .20 to 2.12/1.02.29 via vanilla 1.02.20. I can't help thinking that what you get from 1.02.29 > 2.12/1.02.20 would not be identical to 1.02.29 > 1.02.20 > 2.12/1.02.20.
