How to migrate data & settings from one firebase to another?

Question

Are there any tools to aid in data migration from dev to staging to prod? If not, are there plans to build them?

I know you can Export JSON and Import JSON from Forg

If you want an option that doesn't require cURL, and you have the firebase-tools project installed, you can run this:

firebase database:get --export -o backup.json /

Note that this should be run from a working directory configured as a Firebase project. The advantage of this option is it will use the Auth you've set up for that project, so you don't need to hard-code auth keys into command lines (for the security-conscious) and it doesn't rely on the deprecated auth-key pattern.

Command-line Fu: Another cool technique if you want separate files for each top-level key is calling:

for i in `firebase database:get --shallow / | jq -r 'keys[]'`; do
    echo "Downloading $i..."
    firebase database:get --export -o $i.json /$i
done

You will need the "jq" tool installed for this to work. Exporting each collection separately can be really useful if you later want to restore or work with just a portion of your data.
