Migration of Red Hat Enterprise Linux 5 or 6 to Red Hat Enterprise Linux 7 with the Preupgrade Assistant

This article describes how an administrator can migrate Red Hat Enterprise Linux 5 or Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7 with the help of the Preupgrade Assistant. The Preupgrade Assistant is a tool which assesses your running system for anything that might adversely affect the success of your migration.

As Red Hat Enterprise Linux 5 will have only extended update support after March 2017, administrators will find a tool like that useful to help them migrate their systems to Red Hat Enterprise Linux 7. The migration from Red Hat Enterprise Linux 5 to Red Hat Enterprise Linux 6 is not covered by the Preupgrade Assistant, nor is it planned.

Microservices are becoming a new trend, thanks to the modularity and granularity they provide on top of advantages like releasing applications in a continuous manner. There are various platforms and projects that are rising which aims to make writing and managing microservices easy.

The application will be a super simple To-Do management list. So, let’s have take a look at what we are going to build and how we are going to build.

Editor’s note: This article references Fedora, which is the upstream project for Red Hat Enterprise Linux (RHEL) — now free for developers. This tutorial should also work on RHEL, just replace ‘dnf’ with ‘yum’ wherever appropriate.
