Upgrade to InfluxDB 3 Enterprise

Stop InfluxDB 3 Core

Stop the running Core process:

# If running in foreground, press Ctrl+C
# If running in background, find and stop the process
pkill -f "influxdb3 serve"

Install InfluxDB 3 Enterprise

Run the quick install script for Enterprise:

curl -O https://www.influxdata.com/d/install_influxdb3.sh \
&& sh install_influxdb3.sh enterprise

Start InfluxDB 3 Enterprise

Start Enterprise with your existing data directory. Enterprise requires a --cluster-id option that Core doesn’t use:

influxdb3 serve \
  --node-id 
NODE_ID
 \
  --cluster-id 
CLUSTER_ID
 \
  --object-store file \
  --data-dir 
DATA_DIR
 \
  --license-email 
EMAIL_ADDRESS

Replace the following:

• NODE_ID: Your existing node identifier from Core
• CLUSTER_ID: A new cluster identifier for Enterprise–for example, cluster0
• DATA_DIR: The same data directory you used with Core
• EMAIL_ADDRESS: Your email address for license activation

When prompted, select your license type (trial or home), then verify your email address.

Verify the upgrade

After starting Enterprise, verify the upgrade was successful:

# Check the version
influxdb3 --version

# Verify your license
influxdb3 show license --host http://localhost:8181

Query your existing data to confirm it’s accessible.

Stop the Core container

docker stop 
CORE_CONTAINER_NAME

Replace CORE_CONTAINER_NAME with the name of your InfluxDB 3 Core container.

Pull the Enterprise image

docker pull influxdb:3-enterprise

Start InfluxDB 3 Enterprise

Start Enterprise using the same data volume. Enterprise requires a --cluster-id option and license configuration:

docker run -d \
  --name influxdb3-enterprise \
  -p 8181:8181 \
  -e INFLUXDB3_ENTERPRISE_LICENSE_EMAIL=
EMAIL_ADDRESS
 \
  -v 
DATA_VOLUME
:/var/lib/influxdb3/data \
  -v 
PLUGIN_VOLUME
:/var/lib/influxdb3/plugins \
  influxdb:3-enterprise \
  influxdb3 serve \
    --node-id 
NODE_ID
 \
    --cluster-id 
CLUSTER_ID
 \
    --object-store file \
    --data-dir /var/lib/influxdb3/data

Replace the following:

• EMAIL_ADDRESS: Your email address for license activation
• DATA_VOLUME: The same data volume you used with Core
• PLUGIN_VOLUME: The same plugin volume you used with Core
• NODE_ID: Your existing node identifier from Core
• CLUSTER_ID: A new cluster identifier for Enterprise–for example, cluster0

  influxdb3:

docker compose down
docker compose up -d

Verify the upgrade

After starting Enterprise, verify the upgrade was successful:

# Check the version
docker exec influxdb3-enterprise \
  influxdb3 --version

# Verify your license
docker exec influxdb3-enterprise \
  influxdb3 show license --host http://localhost:8181

# Check the version

Stop InfluxDB 3 Core

sudo systemctl stop influxdb3-core

Install InfluxDB 3 Enterprise

First, remove the Core package (this doesn’t remove your data or configuration):

# Debian/Ubuntu
sudo apt-get remove influxdb3-core  # doesn't remove /var/lib/influxdb3 or /etc/influxdb3
sudo apt-get update && sudo apt-get install influxdb3-enterprise

# RHEL/CentOS/Fedora
sudo yum remove influxdb3-core  # doesn't remove /var/lib/influxdb3 or /etc/influxdb3
sudo yum install influxdb3-enterprise

Configure InfluxDB 3 Enterprise

The Enterprise package installs a self-documenting configuration file at /etc/influxdb3/influxdb3-enterprise.conf. Merge your Core settings into this file rather than overwriting it.

1. View the settings you configured in Core:

   # Show uncommented (active) settings from Core configuration
   sudo grep -E '^ *[^#]' /etc/influxdb3/influxdb3-core.conf

2. Merge Core settings into the Enterprise configuration:

   # Back up the original Enterprise configuration
   sudo cp /etc/influxdb3/influxdb3-enterprise.conf \
           /etc/influxdb3/influxdb3-enterprise.conf.orig
   
   # Merge settings from Core into Enterprise config
   sudo grep -E '^ *[^#]' /etc/influxdb3/influxdb3-core.conf | while IFS= read -r line; do
     key=$(echo "$line" | sed 's/=.*/=/')
     if sudo grep -qE "^ *${key}" /etc/influxdb3/influxdb3-enterprise.conf; then
       # Update existing uncommented line
       sudo sed -i "s|^ *${key}.*|${line}|" /etc/influxdb3/influxdb3-enterprise.conf
     else
       # Replace commented line with active setting
       sudo sed -i "s|^#${key}.*|${line}|" /etc/influxdb3/influxdb3-enterprise.conf
     fi
   done

3. Add your license email to the Enterprise configuration:

   sudo sed -i 's|^#license-email.*|license-email = "
   EMAIL_ADDRESS
   "|' \
     /etc/influxdb3/influxdb3-enterprise.conf

   Replace EMAIL_ADDRESS with your email address for license activation.

4. Verify the merged configuration:

   sudo grep -E '^ *[^#]' /etc/influxdb3/influxdb3-enterprise.conf

   The output should include your Core settings plus the license email and cluster ID–for example:

   node-id = "primary-node"
   object-store = "file"
   data-dir = "/var/lib/influxdb3/data"
   plugin-dir = "/var/lib/influxdb3/plugins"
   cluster-id = "primary-cluster"
   license-email = "you@example.com"

   The DEB/RPM packages use primary-node and primary-cluster as defaults, matching the behavior of running influxdb3 serve without --node-id or --cluster-id.

Start InfluxDB 3 Enterprise

sudo systemctl start influxdb3-enterprise

Check the logs to verify the server started successfully:

journalctl --unit influxdb3-enterprise -f

After starting, check your email and click the verification link to activate your license.

Verify the upgrade

After starting Enterprise, verify the upgrade was successful:

# Check the version
influxdb3 --version

# Verify your license
influxdb3 show license --host http://localhost:8181
