What would be the best approach to migrate FROM InfluxCloud to my own InfluxDB Instance.
Obviously, the influxd backup/restore functionality would be perfect, but that one does not work on InfluxCloud as stated on their documentation
I've recently had to do something similar and used the following approach.
Use a CURL request to output the collection in a json file
curl "https://CLOUD-ENDPOINT.influxcloud.net:8086/db/DATABASE_NAME/series?u=USERNAME&p=PASSWORD&q=select%20*%20from%20DATABASE_NAME%3B" > output.json
Replace CLOUD_ENDPOINT, DATABASE_NAME, USERNAME and PASSWORD with the correct values.
Convert the json file to Line protocol. There already exist a lot of scripts for this. Example: influx-json2line
