Re: Upgrade from el4 to el5

If you want to change from version 4 to version 5, you have to do a upgrade installation. up2date is for updating packages in the same release.

Re: Upgrade from el4 to el5


up2date is a tool for updating within rhel 4, to get to the latest version.

If you download and burn media for rhel 5, you can boot off that media and will be offered an upgrade option in the installation menu.

upgrade is not perfect and all applications that worked before the upgrade might not work after.
