We upgrade for various reasons, whether being able to get support for the products we run, getting (and keeping) needed functionality, or improving performance. This fact means that for those of us in the system administration profession, upgrading software is a constant activity. You want to be able to return to the original state if you run into problems. If you run Satellite on Red Hat Enterprise Linux running bare metal, take a full backup. If you run Satellite as a virtual machine (in whatever VM system you use) take a backup or a snapshot. This article describes the high points of the process and includes lessons learned from updating and upgrading my Red Hat Satellite server. If any problems occur, we need to spot and solve them quickly so that the developers can continue their work uninterrupted. Our Satellite server is often used during the development cycle, so we have to know it’s working correctly. This feature becomes important for our software development process, because we need to quickly create and destroy virtual machines in service to the development process. Satellite hosts repositories locally so we can get those updates faster and for a larger number of clients. Red Hat Satellite provides a means for updating Red Hat Linux systems with new or updated RPMs. Editor's note: This article was written while James Brigman was a member of the Red Hat Accelerator program.
