TIL; though I moved my servers to Debian ... having the ability to sanely upgrade without a reinstall is a major plus.
@Dark_Arc @LeFantome I've had mixed luck with debian in this regard. Bullseye to Bookworm was a smooth upgrade but some of the others have not gone so well.
I'm pretty sure Alma had a way to upgrade major releases. I know RHEL has Leapp, but it is always recommended to do a greenfield reinstall. Although with image mode and ostree that is changing.
Interesting ... yeah it looks like Leapp can do some upgrades for Alma and possibly others as well (TIL). I'm not sure how well that upgrade process would compare / be supported vs Debian though.
What's the image mode and ostree stuff? Is that required for RHEL and/or Alma going forward?
