+
+Multi-version connector support lets you control which connector version is used in your Aiven for Apache Kafka Connect® service.
+It prevents compatibility issues from automatic updates, avoids breaking changes
+when multiple dependencies rely on a specific connector version, and allows testing,
+upgrading, or reverting versions to maintain production pipeline stability. You can
+specify the version of a connector by setting the `plugin_versions` property in the
+service configuration.
+
+## Key considerations for multi-version connectors
+
+- Deprecated connector versions may be removed during maintenance updates. If you
+ [pin](#pin-version) a deprecated version, the system alerts you and recommends an
+ upgrade. The connector will continue to run, but upgrading to a supported version is
+ recommended to avoid compatibility issues.
+- Support is limited to the latest connector version and the most recent previous
+ version. Breaking changes, if any, are detailed in
+ [maintenance update notifications](/docs/platform/concepts/maintenance-window#maintenance-updates).
+- Pinning a connector version applies to the entire plugin, ensuring that all
+ connectors provided by the plugin (such as source and sink connectors) use the same
+ version.
+- Multi-version support is available for all connectors where Aiven has published and
+ supports more than one version. Support will continue to expand as new versions are
+ released.
+- If no version is pinned, the latest available version is used.
+- Refer to [Check available connector versions](#check-available-connector-versions) to
+ confirm which versions are supported before pinning a version.
+
+## Supported connectors and versions
+
+:::note
+All versions listed in the table are supported unless explicitly noted otherwise.
+:::
+
+
+| Connector | Versions |
+|---------------------|-----------------------|
+| Debezium | `2.5.0` (recommended)
`1.9.7` (deprecated) |
+| JDBC | `6.10.0` (recommended)
`6.9.0` (deprecated) |
+| Snowflake | `2.3.0` (recommended)
`2.2.0` |
+
+
+:::tip
+This is a partial list of connectors, and it may change as new versions are released. To
+view the most up-to-date versions, see
+[Check available connector versions](#check-available-connector-versions).
+:::
+
+:::note
+If you are using version `1.9.7` of the Debezium connector, you can upgrade to
+version `2.5.0` without raising a support ticket. To upgrade, pin version `2.5.0` in
+your configuration. For details, see [Pin a connector version](#pin-version).

+
+## Prerequisites
+
+- [Aiven for Apache Kafka® service](/docs/products/kafka/kafka-connect/howto/enable-connect)
+ with a [dedicated Aiven for Apache Kafka Connect® service](/docs/products/kafka/kafka-connect/get-started#apache_kafka_connect_dedicated_cluster)
+ enabled
+- [Aiven CLI](/docs/tools/cli)
+- [Aiven API](/docs/tools/api)
+- [Aiven Provider for Terraform](/docs/tools/terraform)
+
+:::note
+Multi-version support is only available for **dedicated Kafka Connect services**. Ensure
+that your service is updated to enable this feature.

+
+## Check available connector versions {#check-available-connector-versions}
+
+Before pinning a connector version, check which versions are available for your
+Apache Kafka Connect service. Verify if a connector supports multi-versioning by
+reviewing the listed versions. Use one of the following methods:
+
+
+
+
+
+1. Run the following command:
+
+ ```bash
+ curl -X GET "https://api.aiven.io/v1/project//service//available-connectors" \
+ -H "Authorization: Bearer "
+ ```
+
+1. Review the response to see the available versions. If multiple versions are listed,
+ the connector supports multi-versioning.
+
+ Example output:
+
+ ```json
+ {
+ "plugin_name": "aiven-kafka-connect-jdbc",
+ "available_versions": [
+ {
+ "version": "6.10.0",
+ "deprecated": false
+ },
+ {
+ "version": "6.9.0",
+ "deprecated": true
+ }
+ ]
+ }
+ ```
+
+
+
+
+1. Run the following command:
+
+ ```bash
+ avn service connector available
+ ```
+
+1. Review the output to see the available versions. If multiple versions are listed,
+ the connector supports multi-versioning.
+
+ Example output:
+
+ ```json
+ {
+ "plugin_name": "aiven-kafka-connect-jdbc",
+ "available_versions": [
+ {
+ "version": "6.10.0",
+ "deprecated": false
+ },
+ {
+ "version": "6.9.0",
+ "deprecated": true
+ }
+ ]
+ }
+ ```
+
+
+
+
+In Terraform, you can specify the desired connector version using the `plugin_versions`
+attribute in your configuration. This ensures that your Apache Kafka Connect service
+uses the exact version you need.
+
+For detailed steps and examples, see [Pin a connector version](#pin-version).
+
+
+
+
+## Pin a connector version {#pin-version}
+
+To use a specific connector version, update the `plugin_versions` property in the
+service configuration. Pinning a **plugin version** applies to all connectors
+(source and sink) provided by that plugin. For example, pinning
+the `aiven-kafka-connect-jdbc` plugin to version `6.9.0` affects both the JDBC source
+and sink connectors.
+
+:::note
+Pinning a plugin version restarts Apache Kafka Connect and reloads all plugins.
+Allow time for the process to complete.
+:::
+
+
+
+
+1. Run the following command:
+
+ ```bash
+ curl -X PUT "https://api.aiven.io/v1/project//service/" \
+ -H "Authorization: Bearer " \
+ -H "Content-Type: application/json" \
+ -d '{
+ "plugin_versions": {
+ "": ""
+ }
+ }'
+ ```
+
+ Parameters:
+
+ - ``: Aiven project name.
+ - ``: Apache Kafka Connect service name.
+ - ``: Aiven API token.
+ - ``: Plugin name. For example, `aiven-kafka-connect-jdbc`.
+ - ``: Desired version of the plugin. For example, `6.9.0`.
+
+1. Verify the update in the service configuration:
+
+ ```bash
+ curl -X GET "https://api.aiven.io/v1/project//service/" \
+ -H "Authorization: Bearer "
+ ```
+
+
+
+
+1. Run the following command:
+
+ ```bash
+ avn service update --project \
+ -c 'plugin_versions={"": ""}'
+ ```
+
+ Parameters:
+
+ - ``: Apache Kafka Connect service name.
+ - ``: Aiven project name.
+ - ``: Plugin name. For example, `aiven-kafka-connect-jdbc`.
+ - ``: Desired version of the plugin. For example, `6.9.0`.
+
+1. Verify the update:
+
+ ```bash
+ avn service get
+ ```
+
+
+
+
+1. Update your Terraform configuration:
+
+ ```hcl
+ resource "aiven_service" "kafka_connect" {
+ service_name = ""
+ project = ""
+
+ user_config {
+ plugin_versions = {
+ "" = ""
+ }
+ }
+ }
+ ```
+
+ Parameters:
+
+ - ``: Apache Kafka Connect service name.
+ - ``: Aiven project name.
+ - ``: Plugin name. For example, `aiven-kafka-connect-jdbc`.
+ - ``: Desired version of the plugin. For example, `6.9.0`.
+
+1. Apply the changes:
+
+ ```bash
+ terraform apply
+ ```
+
+1. Confirm the updated configuration:
+
+ ```bash
+ terraform show
+ ```
+
+For detailed information, refer to the
+[Terraform Registry - `plugin_versions`](https://registry.terraform.io/providers/aiven/aiven/latest/docs/resources/kafka_connect#plugin_versions-1).
+
+
+
+
+## Verify the connector version
+
+After pinning a version, confirm that the correct version is in use.
+
+
+
+
+1. Run the following command:
+
+ ```bash
+ curl -X GET "https://api.aiven.io/v1/project//service/" \
+ -H "Authorization: Bearer "
+
+ ```
+
+1. Review the `plugin_versions` property in the response to verify the pinned version.
+
+
+
+
+1. Run the following command:
+
+ ```bash
+ avn service get
+ ```
+
+1. Check the `plugin_versions` property in the output to confirm the version.
+
+
+
+
+Verify the version in your Terraform state or configuration after applying changes:
+
+1. Run:
+
+ ```bash
+ terraform show
+ ```
+
+1. Locate the `plugin_versions` property under the Kafka Connect service resource.
+ It displays the pinned version of the connector.
