Hi!
I've got a 32-bit Centos installed on an AMD Phenom II X2 processor and I'm interested ni making it 64 bit instead. But I'd sure like to avoid having to go back thru the whole installation again... in part because I've got sotware RAID set up and I'm assuming that I can't do a fresh install into it without having to re-configure the whole thing.
Doing a fresh 64 install on an existing 32-bit system with software RAID does not mean you have to re-configure the RAID system.
Are you using LVM? Have you broken up your root, /boot, and /home (and possibly /var/<mumble>) as separate file systems (except /boot) as LVM logical volumes? If so, it is easy. I did this recently. I created fresh root, /usr, and /var filesystems (lvcreate ...), then installed 64-bit CentOS 5.4. I retailed the old 32-bit CentOS 4.8 system tree and copied the config files needed to bring the 64-install up to speed..
So, is it possible (and practical) to upgrade a 32 bit system to 64?
Not recomended to 'upgrade'.
Thanks, robert. When the time comes I may drop you a privater email to inquire if you can expand on this.
