I was wondering if there is a tutorial on how to backup and restore all the configuration in application and network server. Recently I’ve decided to transfer my server to a new machine so I figured that this is an opportunity to update to the latest version as well, but I couldn’t seamless integrate the configuration and devices from the old server. I had to do it all over again.
Yes. LoRa Server and LoRa App Server both are using a migrations tool that apply missing schema changes on start (it tracks the migrations that have been applied so that it can detect which missing migrations to apply to your db scheme). See for example this folder: https://github.com/brocaar/lora-app-server/tree/master/migrations.
