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
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.
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
