Overview

TransferGraph is small node.js project to transfer data from one GraphQL instance to another.

You must have already migrated your schema to the new GraphQL instance before this will work.

THIS WILL CLOBBER DATA IN THE TARGET GRAPHQL INSTANCE

Before transfering in the data from the old GraphQL instance, it will clear the data in the new instance!

If your database is complicated, feel free to reimplement main.js with manual calls to clearTable() and transferTableData()

If you want to do a dry run, there is a variable called dryRun you can set to true(if someone wants to submit a PR to turn this into a cli option, please do)

Instructions

1. back up your data by exporting a .json from every table in the hasura console
