Regards, Leonard. That's redhat's way of saying that an upgrade to a major version is like a new install, meaning you should back up your data etc. before installing 6.2. In short, it takes some planning ahead of time to upgrade from 5.8 to 6.2, especially if you've never done such an upgrade before. From prior experience I've found major upgrades easier if, in the current setup, instead of having just one volume/partition and so everything under root (/), there are separate partitions or volumes for (at least) /home and /var because redhat (and so too centos) has always recognized that those partitions contain data and will ask if I want to leave them as they are or, instead, overwrite them. If you currently have just one volume/partition, then you *must* backup any data you want to save and then re-install it you have 6.2 running. If you already have separate volumes/partitions on your 5.8 system, you still will want to note which are which so that when you install 6.2 you will be able to make the correct assignments. There will likely be configuration information you will want to have during the 6.2 install, e.g. your network configuration. So look around under /etc for that and have readable copies of what you will need during the install. That's some of what's involved. It would take more than just a couple paragraphs to explain everything. Much will depend upon what you are currently running and what you plan to run on 6.2. Hope this helps a bit. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I've been caught out before when installing Linux with existing data on several partitions, and had my partitions and data trashed. My work around is to only let the installer use / tmp and swap. That way it cannot touch my partitions with data on them. Once the initial installation is completed I then install my own /etc/fstab from backups. This then allows the new Linux OS to mount those partitions with existing data on them.

I've done at least a dozen, maybe three or four dozen installs, with (actual) redhat, suse, centos, and probably others too, but have never had that happen to me. Linux has even recognized every Windows partition I've had and has left those alone to when I've asked it to. This might be because I always select Custom Install at the very beginning of the process. IMS, if you select New Install (or words to that effect), you don't have the option to select partitions you want to leave untouched during the install. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

IIRC that happened a some years ago with Ubuntu. Ever since that happened I've been wary of the various different custom options available from different Linux distros. I just use the Gparted Live CD to do any partition work. I don't use LVM either yet, so that's not a problem for me now.
