Explore different methods for upgrading from InfluxDB 1.x to InfluxDB {{< current-version >}} and determine which best suits your use case. Consider the following:

Do you want to migrate all your time series data?

Automatically upgrade to InfluxDB {{< current-version >}}.

Do you want to selectively migrate your time series data?

Manually upgrade to InfluxDB {{< current-version >}}.

Are you using Docker?

Upgrade to the 2.x Docker image.

Are you using continuous queries (CQs)?

After you upgrade (automatically, manually, or using Docker), migrate your 1.x CQs to InfluxDB {{< current-version >}} tasks.
