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.
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.
