The CentOS 7 iso is 7.8 gigs. My DVD-R media tops out at about half that. The server I'm trying to upgrade would have to use an external DVD drive in order to upgrade from a DVD.
I am trying to upgrade from CentOS 6.8 to CentOS 7.3. I want to install CentOS 7.3 on a newly installed and unused 500 gig SSD. So far, I have created a 10G ext2 partition at the beginning of the new SSD and I have copied the CentOS 7.3 iso's contents to it. I used a loop mount to mount the iso and then cp -av. I am trying to figure out how to install from a local hard drive instead of a DVD disk. I have Grub 1 in CentOS 6.8, is there a way to trigger the installer from my existing Grub on the second SSD? Can I seamlessly upgrade the old CentOS 6.8 to use Grub 2 instead of Grub 1? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
