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?
