Subject: Re: Upgrading from CentOS 5.6 to 6.0
Help!
Just ran the installation DVD but there is no option to 'upgrade'. Looked at
the RHEL docs,
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installati
on_Guide/ch-guimode-x86.html#id4594292 referenced off the CentOS Release
notes but the CentOS installation doesn't offer the 'upgrade'.
I use to be able to upgrade by doing a 'yum update'. That doesn't work
either.
Guess I'm stuck with 5.6 as I an not about to install a new version and have
to rebuild all non-rpm packages from scratch. This is worse than Microsoft!!
Red Hat does not support upgrades between major versions (doesn't necessarily mean it's not possible)

http://linsec.ca/blog/2011/02/23/my-adventure-upgrading-rhel5-to-rhel6/Since when?? I started with slackware 1.0 on a pentinum 1 system from VaResearch back in the mid 90's, change to Redat 2.0, then Fedora, then to Whitebox, then CentOS.. Never had a problem upgrading on an rpm based system.
Microsoft Windows and Red Hat Linux have a very different release strategies and version numbers. You can read more about the support lifecycle here: https://access.redhat.com/support/policy/updates/errata/
