I know there has been a few topics on this, but basically, with NextCloud 25 now available, it’s important to migrate.
I have a RPI4 but unfortunately I picked the 32 bits version when I installed YNH initially. Now I could of course use a second RPI and do a migration, but I’d be more comfortable migrating the underlying debian 11 from 32 to 64 bits.
So far, all the topics here have been closed without solution…
Totally agree with polochon. I would perform a force-upgrade on apps that fail to start after restoration: yunohost app upgrade <the_app> -F, that makes sure to re-build the apps previously compiled for ARM.
vaultwarden did not restart until after I ran yunohost app upgrade vaultwarden -F
nextcloud had an issue during the re-install which is quite weird (and unrelated to the process): my initial machine has a domain which I changed (and afterward removed the old domain name). There’s a trace of the old domain in nextcloud somewhere which ended up screwing the restoration. I had to re-add nextcloud.myolddomain to the ynh domain list, then the restoration went well!
