From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Solved] Can I upgrade my server directly from Debian 11 to 13 without problems? (programming.dev)

Or should I go 11 > 12 > 13?

Edit: Thanks for all the replies. I asked this out of laziness and apparently trying this is not a lazy thing to do. I'm not Bilbo Baggins seeking an adventure. Will go with 11 > 12 > 13 way, though might stay at 12 for a while at this point. You know, lazy. :)

Edit 2: Updated to 12. Haven't checked all the configs yet but so far so good, at least every function I expect works. If I finish this checking sequence, I might go for 13 soon too.

Edit 3: Updated to 13 as well. It actually took shorter than updating from 11 to 12. Though for some reason Jellyfin is marked as obsolete, however it works and I couldn't care less. My things are working and hopefully I won't see problems. If I do, I'll check them one by one at this point since it's a small home server.

Gotta add this: I had 325 packages on Debian 11, and now I have 450 packages on Debian 13. Some of them are marked as obsolete but must review them one by one. I feel like this upgrade process brake my minimalism and introduced some bloat but gotta care about that later.

Major version changes for any software from the OS right down to a simple notepad app should update as sequentially as possible (11>12>13>etc). Skipping over versions is just asking for trouble, as it's rarely tested throughly.

It might work, but why risk it.

An example: if 12 makes a big database change but you skip over that version, 13 may not recognize the databases left by 11 because 12 had the code to recognize and reformat the old database while that code was seen as unnecessary and removed from 13.

Stuff like this is also why you can't always revert to an older version while keeping the data/databases from the newer software.

Yeah, that makes sense. Major changes in software are no joke. If it wasn't my actual server I could've tried it though, could be a fun thing to pass time.
