Hello Everyone, I'm using Belkin RT3200, installed it a long time ago with OpenWrt 22.03.1, r19777-2853b6d652. I think I am using UBI (this means I converted, so it should be just fine to upgrade?) - please confirm:
root@3200:~# ubinfo
UBI version: 1
Count of UBI devices: 1
UBI control device major/minor: 10:63
Present UBI devices: ubi0
root@3200:~# mount | grep ubi
/dev/ubi0_5 on /overlay type ubifs (rw,noatime,assert=read-only,ubi=0,vol=5)
I should not have problems with kiss of death too - but it's irrelevant if I want to go to new builds of 24.x ?
Would you have some advice on what do I need to take care to safely upgrade?
(apart from backing up configs and so on)
Reflash with the new version, or sysupgrade? (Using openwrt for the most part of last, probably, 15 years on multiple devices, yet I never tried attended sysupgrade)
Which version/image to choose - want newest but stable, my main internet router.
I asked for advice on which version to choose - let me elaborate on that:
does it make sense to try to jump to newest 24 (how risky/buggy the fresh one is?)
As for the link you posted, I've seen the page you listed before and over there it is stated:
Updating to 23 - no need to rerun installer
Updating from 23 - need to rerun installer
Path with saving config is shown from 23->24, and is possible.
However, what I could not find in the link you posted, is if I can sysupgrade from 22 to 23, and then follow with upgrade from 23 to 24 (preserving the config as shown there). Is that a viable path, or should I drop the idea, just save uci config, reflash/use installer and just configure it again?
As a side note, just throwing the links around is not the right way to keep the community spirit. Let's communicate.
Upgrading from 22.x to 24.x is similar to the path from 23.x to 24.x. You do need to run the new UBI installer because of the data layout change. This process cannot retain your old configuration, and you should not try to restore the old configuration once the process is complete. There were also hardware addressing and naming changes between the versions, so attempting to restore an old config in part or in whole will result in complications and problems.
Before you try to perform the upgrade, I strongly recommend you take a backup of the 'factory' mtd partition. It's much easier to do from 22.x, and this data is the only thing on the router that is unique to each individual router and so it can't easily be replaced. If things do go wrong, you'll need that data to restore the router to 100% function.
