Dear all, First of all I'd like to wish all developers/maintainers and users a happy new year and all the best. I know I am quite late with this topic, but other things distracted me so-far: I'd like to finally upgrade our cluster to 11.0. According to the upgrade instructions (https://docs.qlustar.com/en-US/Qlustar_Cluster_OS/11.0/html-single/Release_N...) it is more or less an apt distupgrade; but since there are a lot of changes and I have very bad experience trying to upgrade merely ubuntu-versions (which usually breaks), I can't believe it is so simple? So I'd like to ask whether it is really as simple and what your experiences are? Any caveats, things to keep in mind? Can I do it while calculations are running or should I rather wait for all of them to finish (we have run-times of months, therefore this is a thing in my case). Any advice/comment is very welcome. Best regards, Tobias
