redhat upgrade within same release

If upgrading from one release to another without going to a major release what is the best way to do it with redhat satellite server? Can up2date be run to update all the major packages? How is the kernel package installed?

i haven't used satellite, but up2date can be used to update all packages; you can use RHN to manage your systems and see what packages are available for update and only select those you need or want

it's been a while since i've used RHEL 4 but i do remember manually having to configure up2date on a new system to remove the kernel exclusion; by default kernel updates are not installed.  once you remove that exclusion the kernel packages are included

Please consider to provide the RH versions you are talking about.

For the next I assume you are upgrading from a minor to the next minor version, 6.3 to 6.4 for instance. The by far easiest way is to use plain yum, this is the recommended tool nowadays (EL5+). This assumes your satellites are all synced with the latest packages:
yum update

Open in new window

This will always give you the latest version. After this your system will be 6.4.
You can also use distro sync, this will be the same (basically), but is esp. useful if you have some left over old packages:
yum distro-sync

Open in new window

Though possible, RH does not recommend to upgrade major versions but to do a clean install and restore the data.
You use up2date -l to list available updates and up2date -u to download all update from RHN, assuming you are referring to RHEL4.

I still fail to see where all you guys get the clue that lolaferrari is talking about RHEL4... sorry. RHEL4 is EOL anyway since Feb.2012 for most of us.

But if so, this true, since yum was introduced in RHEL5.
