I don’t believe it is currently possible until someone contributes the API code for it.
It would be nice for sure. We do 99% of the configuration with a bunch of generated ‘lnms config:set …’ command line stuff that gets generated when we cold boot an environment (ie bring up a new mysql instance) - but Transports and Alert rules we manually manage on multiple instances which sucks a little.
From memory when we boot strapped them we mysqldumped a few tables from one instance and restored them. I can’t remember which ones though …
It would be good to have the APIs just to facilitate backups/recover/migration activities etc
