I've done this many times. Just go to a mirror, download and install the centos-release rpm, yum and import the GPG key. Then run 'yum update'. This is a very smooth transition.

Gava Sent: Thursday, June 02, 2005 10:44 PM To: centos at centos.org Subject: [CentOS] rhel3 < centos3 updates Hi all, I've been approached by someone who has an installation of rhel ES 3 (taroon update 2) to see whether I can take over doing security and other updates for them (no current rhn subscription). What I want to know is, with a suitable yum setup can I use a centos3 repository to apply updates to this box? If so, should I source updates from centos 3.5? Does the whole box need to become a centos3 box to do this? They'd really like to disturb the existing box (I agree) as little as possible since it's a stable production server, and mainly just want important security related updates etc. done. Ok, tia for any answers, Stephen. -- Stephen M.
