Downgrade InfluxDB

To downgrade from InfluxDB 2.7 to a previous 2.x version, use the influxd downgrade command to downgrade the metadata schema used by influxd to match the metadata schema of a older release.

InfluxDB does not guarantee backwards-compatibility with older releases in its embedded metadata stores. Attempting to start an older influxd binary with a BoltDB or SQLite file that has been migrated to a newer schema will result in a startup error similar to:

Error: up: reading migrations: migration "...": migration specification not found

To downgrade from InfluxDB 2.7 to a previous 2.x version:

  1. Run influxd downgrade using the 2.7 influxd binary. Specify the previous InfluxDB version to downgrade to. For example, to downgrade to InfluxDB 2.0:

    influxd downgrade 2.0
  2. Install the earlier version of InfluxDB by following the InfluxDB v2 installation instructions.

  3. Start InfluxDB with the earlier versioned influxd binary.

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
