Migrating HP Serviceguard for Linux to Veritas Cluster Server for Linux

This white paper, created with the assistance of HP, illustrates a process to migrate an HP Serviceguard for Linux (SGLX) cluster to Veritas Cluster Server (VCS). An introduction to the architecture of VCS is described including sections comparing SGLX and VCS which contrast cluster terminology and describe architecture differences. A step-by-step process describes how to use configuration information from an existing SGLX cluster to quickly migrate to a VCS cluster with similar functionality.

Introduction
This document is intended to provide information to assist with the migration of a cluster from Serviceguard for Linux (SGLX) to Veritas Cluster Server (VCS) for Linux. HP Serviceguard on Linux is being discontinued and with this document it is our intention to illustrate the migration path to Veritas Cluster Server as an alternative to Serviceguard for Linux. Please review product documentation before installing VCS.

It is a best practice to validate that the current Serviceguard cluster configuration behaves as expected to ensure that the environment is in a known good state before beginning a migration.
