Thank you for installing InfluxDB v2. Due to significant changes between
|
|
the v1 and v2 versions, upgrading to v2 requires additional steps. If
|
|
upgrading to v2 was not intended, simply re-install the v1 package now.
|
|
|
|
An upgrade helper script is available that should be reviewed and executed
|
|
prior to starting the influxdb systemd service. In order to start the v2
|
|
upgrade, execute the following:
|
|
|
|
sudo /usr/share/influxdb/influxdb2-upgrade.sh
|
|
|
|
Visit our website for complete details on the v1 to v2 upgrade process:
|
|
https://docs.influxdata.com/influxdb/v2.0/upgrade/v1-to-v2/
|
|
|
|
For new or upgrade installations, please review the getting started guide:
