Hello,
I have some servers that have lost their RHEL update entitlements. Thinking through it, I realized we may not really need those entitlements. However, I would still like to automate keeping them up to date for security fixes. So, is there any way to swap out the Yum/up2date RHEL repositories for CentOS without breaking things?
see Migration from RHEL5 to CentOS5 near the bottom of http://wiki.centos.org/HowTos/MigrationGuide
if you have 4, its similar but different. if you have 3, time to wipe and upgrade IMHO.
