I have a RHEL system and I'm thinking of changing to CentOW. How can this be done most easily. It is important that the e-mail setup not be disturbed, since it was crafted to work with an IP that requires authentication.
Not sure if this will help, but I went the other way from CentOS to RedHat by grabbing a list of packages with "rpm -qa", cleaning up the package names a bit, installing a base RedHat based on the same update level, then "yum update" or "yum install"ing from the list of packages. Next I diffed the configuration directories and manually moved the changed files. Finally just backed up/restored the database and application LVMs (dd/gzip the entire partition).
