I'd like to upgrade my server's os from RHEL 4 to 6 after 2012/08.
I know that there are 2 methods to upgrade.
1. directly (RHEL 4 -> 6): 1. buy a new server machine. 2. install RHEL6 on the machine. 3. move my system from old machine to new machine. 4. swap these machines. 2. one by one (RHEL 4 -> 5 -> 6): 1. upgrade from RHEL 4 to RHEL 5 with up2date command. 2. upgrade from RHEL 5 to RHEL 6 with yum command.
I'd like to use 2nd method. However, I heard that Redhat was already stopped the support of REHL4 since 2012/03.
Is it possible to upgrade from RHEL 4 to 6 with up2date(or yum) on or after 2012/08?
