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.
It seems nobody really tested 11 to 13, or maybe any kind of major-version-skipping and you won’t find direct experiences here.
Your best bet is to follow the official procedure, so 11 -> 12 -> 13. I’ll leave you with the official upgrade guide for 11 to 12 and 12 to 13.
It seems longer than it is, as not every step is actually required for every system. When upgrading VMs, a snapshot pre-upgrade can also help you skip backup-steps in the guides.
Well, certainly not gonna be a tester. If it isn’t tested, there is no need to take things further. Thanks for the guides by the way.
