RHEL4 Subscription Upgrades

By Erik Rodriguez

This article describes the options of changing your subscription from RHEL3 to RHEL4 in regards to the Redhat Network.


Problem

Initially, I was worried that I would have to pay another subcription fee for RHEL4. However, there are several options available within you RHN account.

First, remember that your subscription to RHEL covers calendar years, and not OS versions. Soposedly, Red Hat supports the Enterprise Linux version for 7 to 8 years. If you purchase 1 subscription, you can actually update 2 systems. Each "subscription" gives you entitlement to updates and management. The only difference between the two, is that systems registered to management will automatically update themselves. Any system registered to do updates, will simply allow you to login to the RHN and fetch the updates manually. They will install automatically, but you must intiate the update. Management really shines when you need packages installed, and things scheduled. You cannot schedule a reboot on systems only registered to do updates.

If you have upgraded your RHEL3 system to RHEL4, simply login to your RHN account. Next click on the system name and chose "delete system." Once you have removed the system, login from the console to re-register the system with a RHEL4 channel. You have the option during the "up2date" setup to "use one of my existing subscriptions." Since the OS is fairly new, the update is rather small.
