The functionality is quite different between 3.3 and 2.1, so regardless of how you do it, it is very likely that you will not be able to rollback successfully. Unfortunately, since both versions are no longer updated, there is nothing we can do about it, so I am afraid to say, but it would be faster for you to recreate the skeleton.

Well ,It's just I tried this a lot times before, it usually worked well after being rollbacked. But this time comes in problem and I don't know why. Thank you anyway.

The problem you are seeing is due to the fact that between v2 and v3 the way flipping is handled changed. in v3 you flip by scaling to negative 1 a bone or image, in v2 there is a checkbox in the property of the bones.
Likely, what you're describing can be fixed by identifying the keys that are supposed to be flipped and fix them.
