Upgrade from InfluxDB 1.x to InfluxDB 2.0
influxd upgrade command to upgrade InfluxDB 1.x to InfluxDB 2.0.
upgrade command provides an in-place upgrade from InfluxDB 1.x to InfluxDB 2.0.
We are working on the upgrade process to ensure a smooth upgrade from InfluxDB 1.x to InfluxDB 2.0 on Docker. If you’re upgrading from InfluxDB 1.x on Docker, we recommend waiting to upgrade until we finalize an updated Docker release given the current process is undefined.
Specifically, the upgrade process does the following:
- Reads the existing InfluxDB 1.x configuration file and generates an equivalent InfluxDB 2.0 configuration file at
- Upgrades metadata and storage engine paths to
~/.influxdbv2/engine, respectively (unless otherwise specified).
- Writes existing data and write ahead log (WAL) files into InfluxDB 2.0 buckets.
- Creates database and retention policy (DBRP) mappings required to query data with InfluxQL.
- Reads existing metadata and migrates non-admin users, passwords, and permissions into a 1.x authorization–compatible store within
When starting InfluxDB 2.0 after running
influxdb upgrade, InfluxDB must build a new time series index (TSI).
Depending on the volume of data present, this may take some time.
Before you begin: important considerations
Before upgrading to InfluxDB 2.0, consider the following guidelines. Some or all might apply to your specific installation and use case. The sections below contain our recommendations for addressing possible gaps in the upgrade process. Consider whether you need to address any of the following before upgrading.
- Available operating system, container, and platform support
- Continuous queries
- Supported protocols
- User migration
- Other data
- Secure by default
Available operating system, container, and platform support
InfluxDB 2.0 requires 64-bit operating systems.
InfluxDB 2.0 is currently available for macOS and Linux. Docker images, ARM builds, and Windows builds are not currently available, but are planned for subsequent releases.
Continuous queries are replaced by tasks in InfluxDB 2.0.
influxd upgrade writes all continuous queries to
To convert continuous queries to InfluxDB tasks, see
Migrate continuous queries to tasks.
InfluxDB 2.0 doesn’t directly support the alternate write protocols supported in InfluxDB 1.x (CollectD, Graphite, OpenTSDB, Prometheus, UDP). Use Telegraf to translate these protocols to line protocol.
You can continue to use Kapacitor with InfluxDB OSS 2.0 under the following scenarios:
- Kapacitor Batch-style TICKscripts work with the 1.x read compatible API. Existing Kapacitor user credentials should continue to work using the 1.x compatibility API.
- InfluxDB 2.0 has no subsriptions API and does not support Kapacitor stream tasks. To continue using stream tasks, write data directly to both InfluxDB and Kapacitor. Use Telegraf and its InfluxDB output plugin to write to Kapacitor and the InfluxDB v2 output plugin to write to InfluxDB v2.
Example Telegraf configuration
# Write to Kapacitor [[outputs.influxdb]] urls = ["http://localhost:9092"] database = "example-db" retention_policy = "example-rp" # Write to InfluxDB 2.0 [[outputs.influxdb]] urls = ["http://localhost:8086"] database = "example-db" retention_policy = "example-rp" username = "v1-auth-username" password = "v1-auth-password"
influxd upgrade migrates existing 1.x users and their permissions.
However, it does not migrate administrative users.
To review users with admin permissions, in the InfluxDB 1.x CLI, run
Any users labeled “admin” will not be migrated.
If using an admin user for visualization or Chronograf’s administrative functions, create a new read-only user before upgrading. Admin rights are granted to the primary user created in the InfluxDB 2.0 setup process which runs at the end of the upgrade process. This provides you with the opportunity to re-assess who should be granted admin-level access in your InfluxDB 2.0 setup.
You can continue to use your existing dashboards and visualization tools with InfluxDB 2.0 via the 1.x read compatibility API. The upgrade process creates DBRP mappings to ensure existing users can execute InfluxQL queries with the appropriate permissions.
However, if your dashboard tool is configured using a user with admin permissions, you will need to create a new read-only user with the appropriate database permissions before upgrading. This new username and password combination should be used within the data source configurations to continue to provide read-only access to the underlying data.
Ensure your dashboards are all functioning before upgrading.
_internal database is not migrated with the
influxd upgrade command.
To collect, store, and monitor similar internal InfluxDB metrics,
create an InfluxDB 2.0 scraper
to scrape data from the
/metrics endpoint and store them in a bucket.
Secure by default
InfluxDB 2.0 requires authentication and does not support the InfluxDB 1.x
auth-enabled = false configuration option.
Before upgrading to 2.0, enable authentication in your InfluxDB 1.x instance and test your credentials to ensure your applications, agents, and visualization tools can connect to InfluxDB.
If you upgrade with
auth-enabled = false, the upgrade may appear complete,
but client requests to InfluxDB 2.0 may be silently ignored (you won’t see a notification the request was denied).
Perform the upgrade
If you’ve considered the guidance above and are ready to proceed, follow these steps to upgrade your InfluxDB 1.x to InfluxDB 2.0.
- Download InfluxDB OSS 2.0.
Unpackage the InfluxDB binaries and place them in your
Stop your running InfluxDB 1.x instance. Make a backup copy of all 1.x data before upgrading:
cp -R .influxdb/ .influxdb_bak/
influxd versionto ensure you are running InfluxDB 2.0 from the command line. The
influxd upgradecommand is only available in InfluxDB 2.0.
If your 1.x configuration file is at the default location, run:
If your 1.x configuration file is not at the default location, run:
influxd upgrade --config-file <path to v1 config file>
Follow the prompts to set up a new InfluxDB 2.0 instance.
Welcome to InfluxDB 2.0 upgrade! Please type your primary username: <your-username> Please type your password: Please type your password again: Please type your primary organization name: <your-org> Please type your primary bucket name: <your-bucket> Please type your retention period in hours. Or press ENTER for infinite: You have entered: Username: <your-username> Organization: <your-org> Bucket: <your-bucket> Retention Period: infinite Confirm? (y/n): y
The output of the upgrade prints to standard output.
It is also saved (for troubleshooting and debugging) in the current directory to a file called
upgrade.log located in the home directory of the user running

influxd upgrade reference documentation.
