Migrate specific InfluxDBv2 buckets of one org from one server to another

influxdbv2-migrate.sh

#!/bin/bash

# InfluxDBv2 migration script
# Copies specific chosen buckets of one org from one server to another
# Guidance:
#   Run this script on a machine running the server with the source data
#
#   The Influx CLI ('influx') must be configured with an active
#     profile for the remote server. Operator perms are ideal;
#     without then you'll need to create the buckets manually
#
#   Manually configure retention policy on new server after migration
#
#   Running this script multiple times will simply append any new data that
#     exists (errors about creating existing buckets can be ignored)

# Source buckets must be configured with bucketname;bucketid
buckets=('bucket1;1ed3c2bdf95bd08f' \
        'bucket2;710d77fe74c18910' \
)

        IFS=';' read -a data <<< $bucket
        bucketname=${data[0]}
        bucketid=${data[1]}
