Well one obvious way is to take the first puzzle and create the second puzzle by applying any isomorphism on the digits of the first puzzle, such that no digit is transformed into itself. eg
1 2 3 4 5 6 7 8 9 could be replaced by
9 1 2 3 4 5 6 7 8
Is this what you are looking for ? Leren
<edit>
I just thought of another way of achieving what I think you want. Instead of a number morph you can swap the rows and columns around.
For example, In the top tier of boxes you can rearrange Rows 1, 2 & 3 in the order 2 1 3, 2 3 1 or 3 1 2. Do a similar thing for Rows 4-6 and 6-9 and you're golden.
You can also do a similar thing with the columns and a similar thing with the tiers and stacks of boxes.
