Best means of upgrade

[Bill Davidsen]

I have a server running a 32 bit release and some critical VMs, so I really 
don't want to mess it up. It also has an old 64 bit (FC6) release which I get to 
via chain loader from the grub in 32 bit. I want to upgrade the 64 bit (which I 
don't use) to the FC13 pre stuff from a daily spin.

The config is thus, 32 bit boot is in a raid-1 array, as is the 64 bit boot. 
Those are based on primary partitions. Then there is a raid-6 array with LVM on 
it, providing /home, and Root32 and Root64 LVs. I want to put the latest 64 bit 
on the array for /boor64 and the LV for /Root64. I do *NOT* want to hose the 32 
bit or MBR!

My choices are:
1 - try to do an upgrade from FC6 to FC13 over the 64 bit install
2 - do a fresh fc13 install, also over the 64 bit old stuff
3 - do it on another machine, too likely to hose the production stuff
     (do it on the fc10 bits of a laptop which is not critical)

Any relevant thoughts on doing the install so I can be sure I can continue to 
use the chain loader from the 32 bit production stuff?
