We have our icinga2 currently running in SLES 12.
We tried to do an inplace upgrade to SLES15, but this went terribly wrong…
Is there a guide how to upgrade the OS under icinga2 or a guide how to migrate the complete configuration to a new machine?
I am afraid that if you want to upgrade to a newer SLES version, and you don’t have a support contract with us, you’ll have to go through the process of getting a repository subscription for the packages.
If you want more information you can find that on our subscription page
If you want to learn more about our reasoning and thought process about the change you can read more about it in our initial blogpost about the topic.
