Upgrade to InfluxDB 1.8.x

This page documents an earlier version of InfluxDB. InfluxDB v2 is the latest stable version.

We recommend enabling Time Series Index (TSI) (step 3 of Upgrade to InfluxDB 1.8.x). Switch between TSM and TSI as needed. To learn more about TSI, see:

Note: The default configuration continues to use TSM-based shards with in-memory indexes (as in earlier versions).

Upgrade to InfluxDB Enterprise

To upgrade from InfluxDB OSS to InfluxDB Enterprise, contact InfluxData Sales and see Migrate to InfluxDB Enterprise.

Upgrade to InfluxDB 1.8.x

  1. Download InfluxDB version 1.8.x and install the upgrade.

  2. Migrate configuration file customizations from your existing configuration file to the InfluxDB 1.8.x configuration file. Add or modify your environment variables as needed.

  3. To enable TSI in InfluxDB 1.8.x, complete the following steps:

    1. If using the InfluxDB configuration file, find the [data] section, uncomment index-version = "inmem" and change the value to tsi1.

    2. If using environment variables, set INFLUXDB_DATA_INDEX_VERSION to tsi1.

    3. Delete shard index directories in your InfluxDB data/ directory. For example, in a Linux environment:

      /var/lib/influxdb/data/<db-name>/<rp-name>/<shard_ID>/index
      
    4. Build TSI by running the influx_inspect buildtsi command.

      Run the buildtsi command using the user account that you are going to run the database as, or ensure that the permissions match afterward.

  4. Restart the influxdb service.

Switch index types

Switch index types at any time by doing one of the following:

Downgrade InfluxDB

To downgrade to an earlier version, complete the procedures above in Upgrade to InfluxDB 1.8.x, replacing the version numbers with the version that you want to downgrade to. After downloading the release, migrating your configuration settings, and enabling TSI or TSM, make sure to rebuild your index.

Note: Some versions of InfluxDB may have breaking changes that impact your ability to upgrade and downgrade. For example, you cannot downgrade from InfluxDB 1.3 or later to an earlier version. Please review the applicable version of release notes to check for compatibility issues between releases.

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.
