    Data Transmission Service:Convert a sync instance to a serverless instance

    Last Updated:Sep 04, 2025

    This topic describes how to convert a Data Transmission Service (DTS) sync instance to a serverless instance.

    Prerequisites

    The sync instance that you want to convert to a serverless instance must meet the following conditions:

    • The Database Type of the source database instance is not PostgreSQL, PolarDB for PostgreSQL, or PolarDB (Compatible with Oracle).

    • The instance meets the requirements for supported regions and limits of serverless instances.

    • The instance status is Running or Paused.

    • The billing method of the instance is pay-as-you-go.

      Note

      If the billing method of the instance is subscription, you must convert it to pay-as-you-go. For more information, see Switch between billing methods.

    • Ensure that the log information for the specified offset exists in the source database. Otherwise, the instance may fail to run and cannot be recovered.
