changing MD device

[Aaron Gee <cluge1669@netscape.net>]

I have a system up and running, the root directory is mounted on device 
/dev/md0 which is a raid1 of 2 IDE drives.  My question is, how can I 
change it so that the my raid device is /dev/md1 not /dev/md0 and not 
loose the data.  Originally I was thinking of booting with a rescue 
disk, breaking the raid1, and rebooting.  Once rebooted create the raid 
device again as /dev/md1.  Is there a simpler way to do this? 

Why do I want to do this?  I have several external FC arrays with 
software raid, and XFS file systems using an external log dev that is 
/dev/md0 which is defined as a raid1 on the same array.  I want to be 
able to recover the external arrays - therefore my /dev/md0 on the 
backup machine needs to change to /dev/md1.

TIA
