This sometimes can be quite tricky and take some time and nerves to do correctly. But since SUSE rocks its amazing YaST (Yet Another Setup Tool), you can nail this setup without deep shell skills. In this Blog post I will try to explain you the steps one has to take to prepare a SUSE Enterprise Linux for Upgrading it. To make it more relatable I will document both the Major-Upgrade and the Minor-Upgrade. Additionally I will explain the biggest issues one might face and give you some hints in how to solve them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-prepare-your-suse-sles\">Prepare your SUSE\/ SLES<\/h2>\n\n\n\n<p>The fact that OpenSUSE does not need any subscription means, that there is no need for cleanup at this point of my Blog.

This might sound harder than the one-click online migration, but in reality, it&#8217;s almost as easy as using YaST. The only difference is that you need to boot the server with the desired ISO version. In our example, my SLES 12 SP5 will need to be booted with the SLES 15 SP6 ISO. Depending on your server (and whether it&#8217;s bare metal or a VM), the specifics might vary case by case. In my case, I&#8217;m using a self-built virtualization server with OpenSUSE and running a KVM Server. The only thing I need to do to boot my SLES 15 SP6 ISO, is to mount the ISO file to my VM and disable secure boot. After that, reboot the VM and enter the &#8220;Upgrade&#8221; tab from your ISO. This will then start the step-by-step migration of your system.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"759\" src=\"https:\/\/www.dbi-services.com\/blog\/wp-content\/uploads\/sites\/2\/2025\/02\/Screenshot-2025-02-24-at-17.06.43-1024x759.png\" alt=\"\" class=\"wp-image-37453\" srcset=\"https:\/\/www.dbi-services.com\/blog\/wp-content\/uploads\/sites\/2\/2025\/02\/Screenshot-2025-02-24-at-17.06.43-1024x759.png 1024w, https:\/\/www.dbi-services.com\/blog\/wp-content\/uploads\/sites\/2\/2025\/02\/Screenshot-2025-02-24-at-17.06.43-300x222.png 300w, https:\/\/www.dbi-services.com\/blog\/wp-content\/uploads\/sites\/2\/2025\/02\/Screenshot-2025-02-24-at-17.06.43-768x569.png 768w, https:\/\/www.dbi-services.com\/blog\/wp-content\/uploads\/sites\/2\/2025\/02\/Screenshot-2025-02-24-at-17.06.43-1536x1138.png 1536w, https:\/\/www.dbi-services.com\/blog\/wp-content\/uploads\/sites\/2\/2025\/02\/Screenshot-2025-02-24-at-17.06.43-2048x1517.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>After booting the ISO you will be greeted with these options.
