Hi I am in need of some help. We have some Fedora Core 1 boxes that we needed to migrate to CentOs. We have previously upgraded the RH 7.3 - RH 9 servers with no issues by using Yum and pointing them to CentOS repositories. With Fedora, there's always the issue of Kerberos and the 'missing' libcom_3 that causes the upgrade to fail. Has anyone done it successfully, and is willing to post your step by step? Thanks. Regards CM .
