how to upgrade from RHEL 5.0 to RHEL 5.3?


Hello eveyone.
Well, I have an environment with RHEL 5.0 and I want to upgrade all hosts to RHEL 5.3
How can I do it? I will need a RHN subscription? Or an internet connection to RHN?
Thanks

Hello,

As far as I know you need a RHN subscription in order to upgrade RHEL. And that's a paying subscription if I'm not mistaking. Not sure if you need to add each and every server to the subscription or if you can use the same RHN login and connection for multiple servers.

Kind regards,

Eric

You'll need a net cxn to RHN and a subscription for each machine. More accurately, 1 or more subscriptions (1 subscription can cover >1 system) that cover your machines, but each will need an entry in the RHN DB.
You do have to pay for these...
If you have this set up, then

yum update

as root user should do it. I'd recommend doing backups first; fyi current version is 5.4.

If you can't/won't pay, backup all non-OS stuff and install Centos 5.4 instead; it's a free version of RHEL.

But I need to upgrade to the 5.3 version, not to 5.4, and If I execute the "yum update" command, will it upgrade to the RHEL 5.4 version? How can i do the upgrade to 5.3?
Thanks

Contact RH sales/support. As I understand it, they offer extended support ($$) for specific minor versions.

You could do a clean install with the 5.3 DVD, but then you'll be frozen at that set of packages. You won't be getting bug / security fixes.

As anomie pointed out, you won't get the latest updates eg security(!).
I highly recommend you update all the way.
