Upgrade InfluxDB 3 Core

Upgrade your InfluxDB 3 Core version.

Before you upgrade

Before upgrading your InfluxDB 3 Core instance, review the release notes for compatibility requirements and then plan your upgrade strategy.

Upgrading to InfluxDB 3.10 is a one-way migration

The first time you start InfluxDB 3.10, it automatically upgrades the on-disk catalog format from v2 to v3. After migration, 3.9.x and older binaries are unable to read the new catalog, and fail to start on the same cluster data.

Before upgrading, back up {prefix}/catalogs/ and {prefix}/_catalog_checkpoint. Restoring these objects is the only way to roll back to 3.9.x.

Verify your current version

Before upgrading, verify the InfluxDB 3 Core version running on each node.

CLI Docker

influxdb3 --version
docker exec 
CONTAINER_NAME
 influxdb3 --version

Replace the following:

  • CONTAINER_NAME: The name of your InfluxDB 3 Core container

The command returns version information similar to the following:

influxdb3 3.10.5

Verify your InfluxDB version

Before and after upgrading, verify the InfluxDB 3 Core version running on your instance.
