Clone old nodes (including posts).
Lock old nodes and setup a redirection.
Later or never delete old nodes.
This is ugly but you would keep resource oriented.

I know and I understand.
I was just warning you that you borrow application schemes of existing  
application (e.g. phpbb + mysql).

It can be done another way. It isn't identical. But it could work.

If you try to get generated id and read/write consistency : you  
get ... a database
