# Migrate from InfluxDB v1 or v2

InfluxDB 3 provides compatibility APIs and tools for migrating existing InfluxDB v1 and v2 workloads. Use existing client libraries and tools with minimal changes to your code.

## Write data

InfluxDB 3 supports v1 and v2 compatible write endpoints:

-   **`/api/v2/write`**: Compatible with InfluxDB v2 clients and tools
-   **`/write`**: Compatible with InfluxDB v1 clients and tools

Both endpoints accept line protocol and write data the same way.

For more information, see [Use compatibility APIs to write data](/influxdb3/core/write-data/http-api/compatibility-apis/).

## Query data

InfluxDB 3 supports the v1 HTTP query API for InfluxQL queries:

-   **`/query`**: Compatible with InfluxDB v1 query clients

For more information, see [Use the v1 HTTP query API](/influxdb3/core/query-data/execute-queries/influxdb-v1-api/).

## Client libraries

Use InfluxDB v1 and v2 client libraries with InfluxDB 3 Core:

-   [v2 client libraries](/influxdb3/core/reference/client-libraries/v2/)
-   [v1 client libraries](/influxdb3/core/reference/client-libraries/v1/)
