Upgrading from an ancient version of Home Assistant
Upgrading from an ancient version of Home Assistant
Trying to upgrade from a 2021 release to the latest one, absolutely no idea whether this will work or not...
Originally I abandoned this install because the API I used to integrate a DIY addressable LED strip (controlled by a media player entity, changed colour to match the cover art) was removed and replaced with something else, and I didn't have time to redevelop it.
For a while its been possible to do something pretty similar with WLED - at that point I was just putting off the upgrades to not break anything π
At this point it's probably a better idea to re-install but let's see how this goes!
Quick update if anyone is reading this in future - the upgrade was successful!
Hats off to the HA developers and contributors - even though my install was completely unsupported, the updater pretty much sailed smoothly through everything.
It ended up taking several days to process all the database schema changes, along the way I did need to modify the MySQL InnoDB cache size from 128MiB to 1GiB (not the fault of Home Assistant at all - I didn't set up MySQL correctly π) once that was done things significantly sped up.
Looking forward to all the new features HA has to offer π
Do a backup first, if the update does go south the backup might apply to a new install
On the plus side, if the update works there is a good automated backup system now, so it won't be an issue again, I suppose.
That's going to be a LOT of reading breaking changes.
Thatβs all I could think of. So many changes and things to repair
Honestly probably better to start from scratch. Backup yaml automations and scripts outside of Home Assistant and start over.
Read breaking changes? People don't accidentally hit update as they see the bold BREAKING CHANGE then deal with the consequences of their actions for the next 20-30 minutes?
The only reason I update Home Assistant monthly is so I'm never in the position to have to read more than one months worth of breaking changes.
make a backup, but yeah maybe just reinstall lmao. good luck!
Uh, good luck! It's giving me cold sweats just looking at that version disparity!
If it were me I'd be looking at doing some intermediate upgrades to help it along, if that's even possible. But hey, it might work, please report back!
It's possible from the command line. And how I will do this when I'm eventually forced to.
Oh no ππ what version are you on now?
I remember a looong while ago when I broke my virtualized install by trying to update with too little virtual disk space, had to expand it and manually install the latest core from a shell within the VM. On another occasion the sqlite database completely filled up the virtual disk (I disabled automatic pruning of old data) and that was a pain to export... eventually dumped it into a dedicated MySQL installation and all was well after that.
I've seen that they now have A/B boot (similar to how Android devices do) so hopefully these are issues of the past
Well how did it go?
Still going π database migration has been running for 21 hours so far lol.

Everything has gone smoothly so far. Spent two hours looking through all the release notes and have a loooong list of stuff to sort out as soon as it completes π€
Edit: fix spoiler
Good luck!
I was expecting something like version 0.112 but this is pretty close.
I did a similar jump a while back, actually went quite well, at least via docker. I kept the old image on hand in case I needed to revert.
But yes, backup first.
