How do I copy children of an object to another similar obj?

i.e:

A - B
\
C - D -E -G
\ \
F H
1) copy to I so children of I look like children of A with just with
different parent key of I->

I - B
\
C - D -E -G
\ \
F H

2) Also what's the simplest way to duplicate A entirely to a different primary key.

To clarify the difference between the 1) and 2) is that I's information is not altered when copying children of A to I. With 2) an new parent is created with the same information contained in A.

Please advise as to best solution for both 1 and 2

Thanks,
Garry

any input on this?

Have u got any success? I too need something like that!!!!

I got a reply like RTFM. See if you have better luck. I ended up brute forcing it. Very ugly code that makes hibernate look bad.
