May I strongly suggest that you read up on computers and operating
systems? You don't seem to understand what you're asking - it's like
asking if, from Windows Vista, you can downgrade to NT 4, and expect
anything but text files to be workable.
A subrelease upgrade or downgrade is not that scary - they've been tested
a lot, and that's just yum upgrade. But when a new full release comes out
- like 4, or 5, or 6, you *really* want to back everything up and do a
fresh install; otherwise, there's too many incompatibilities (such as,
say, python 2.x.x and 2.y.x), and you're asking for problems.
