Migrating from RedHat to SUSE Linux Enterprise Server 10

Migrating from RedHat to SUSE Linux Enterprise Server JO (Course 3068) focuses on the main differences between Red Hal Enterprise Linux 4 and SUSE Linux Enterprise Server 10.It enables an experienced Linux administrator familiar with RedHat Enterprise Linux 4 to perform administrative tasks on the SUSE Linux Enterprise Server 10 platform.By covering the administrative details specific to SUSE Linux Enterprise Server 10, this course prepares you to take the Novell Certified Linux Professional 10 (Novell CLP 10) certification practicum test-provided you already have the general Linux knowledge covered in the courses SUSE Linux Enterprise Server 10 Fundamentals (Course 3071). SUSE Linux Enterprise Server 10 Administration (Course 3072), and SUSE Linux Enterprise Server 10 Advanced Administration (Course 3073).This course also covers topics that are not part of the Novell CLP 10 certification, but are of importance in migration scenarios, like iSCSI. OCFS, or specific differences in mail or web server configuration.
