Red Hat Services: Upgrade Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8

Introduction

Red Hat® Enterprise Linux®, the leading commercial Linux distribution in the public cloud, is an intelligent operating system providing businesses with a consistent foundation for the enterprise hybrid cloud that delivers any application on any footprint at any time. Traditionally, organizations reduce system changes and bypass updates to avoid interruptions in day-to-day operations. However, older software versions can become more susceptible to security and stability risks over time, and businesses miss opportunities for new features to improve performance, scale, and manageability. A new strategy is needed to ensure performance and reliability—one that prioritizes controlled evolution over static environments.

The move from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8 represents a significant achievement, balancing technology advancement with enterprise scale and stability. Featuring builtin management fueled by Red Hat Insights, Red Hat Enterprise Linux 8 delivers a faster and easier-to-deploy operating system with enterprise support and security for a common foundation across physical, virtual, cloud, and container platforms. With this control, confidence, and freedom, customers can focus the majority of their time and attention on managing and running applications, regardless of the underlying infrastructure. Nonetheless, a major release upgrade of a Red Hat Enterprise Linux production environment can be complex.

Red Hat Consulting partners with organizations to assist in the transition to Red Hat Enterprise Linux 8, helping them build a reliable process to upgrade and modernize systems. Experienced Red Hat subject matter experts mentor your teams on accelerated upgrade methods and develop a strategic framework that allows you to take advantage of the new version path, reducing risk. With this security-focused and efficient strategy, customers can adopt technology improvements and capabilities in Red Hat Enterprise Linux 8 without the strain on time and effort.

Get started with Red Hat Consulting

Red Hat Consulting helps customers quickly, iteratively, and strategically achieve value while building enterprise-wide capabilities. During a Red Hat Consulting engagement, teams receive training on the technology while learning and adopting methods and skills needed to sustain success now and into the future, even when the engagement is over.

In an initial 6-week engagement, Red Hat Consulting experts help customers discover, design, and initiate a migration pilot of systems from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8.
