Describe your issue
Hello and a good Day
can i restore an App Backup (Flarum) to an other Domain?
throws a lot errors about domain and breaks.
Many thanks for you Yunohosts
Unfortunately no, not directly. You need to re-create the missing domain first (no need to setup the DNS), then restore the app, then change its URL. Finally you may remove the old domain.
thank you Titus, first problem solution. that helps.
Second problem is a show stopper since MySql won’t upgrade on different versions in general. So all backups with MySql bullseye-version will not restore on bookworm.
In that case: you have to go in the backup tararchive /apps/youreapp/backup/db.sql and delete the first line
