[clue-tech] Upgrading HDDs in an LVM configuration?

[William]

List,

I would like to swap a smallish IDE HDD out of an LVM configuration for 
a larger IDE HDD (using RHEL/CentOS).  There are no available IDE slots 
(or power supply D-plugs) on this machine, but I imagine that I can 
temporarily swap the CD-ROM out for the new HDD to copy files off the 
drive-to-be-replaced.  Is this even possible?

I've been reading around with Google's help on how to add new drives to 
LVM configurations and I'm pretty sure I can handle that.  However, 
that's not what I'm doing.  I need to replace an HDD, not simply add a 
new one.  Obviously, I need whatever is on the old drive to be moved to 
the new drive.

Can this be done, and how?

Here's a drive configuration dump (I intend to replace the 13.6G drive 
with a new 200G drive):
