retrieving expired messages

[Bill Tangren]

Hi all,

I am running inn 2.3.2-5, and I had left the expire settings, on one of 
my newsgroups, set to the default, and what I wanted was for them not to 
expire at all. I have made the requisite changes to expire.ctl, and I 
have the expired messages on backup tape. How do I retrieve them? I 
think that renumbering and history file are the big problems. Any ideas 
how to do this, or where to read up on how to do it?
