Migrating from MySQL/Oracle on macOS

The brew install on macOS does not support installing ora2pg, which is required for MySQL/Oracle database schema export. If you are planning to migrate MySQL or Oracle source databases on macOS, install yb-voyager using Docker instead.

Perform the following steps to install yb-voyager using brew for macOS:

  1. Tap the yugabyte Homebrew repository using the following command:

    brew tap yugabyte/tap
    

    The repository contains the formula to build and install yb-voyager on your macOS device.

    Note that the tap yugabyte/yugabytedb has been updated to yugabyte/tap. If you have previously installed yb-voyager using the tap yugabyte/yugabytedb, untap the entry using brew untap yugabyte/yugabytedb, and then tap using the preceding command.

  2. Install PostgreSQL 17 (required for pg_dump and pg_restore) using Homebrew:

    brew install postgresql@17
    

    After installing PostgreSQL 17, Homebrew displays instructions on how to add the PostgreSQL 17 binaries to your shell's PATH. These steps vary depending on your system's Homebrew installation path (for example: /opt/homebrew or /usr/local) and the shell you are using.

    1. Update your PATH by following the exact instructions shown by Homebrew. Following is an example of what Homebrew may display:

      If you need to have postgresql@17 first in your PATH, run:
      echo 'export PATH="/opt/homebrew/opt/postgresql@17/bin:$PATH"' >> ~/.zshrc
      For compilers to find postgresql@17 you may need to set:
      export LDFLAGS="-L/opt/homebrew/opt/postgresql@17/lib"
      export CPPFLAGS="-I/opt/homebrew/opt/postgresql@17/include"
      
    2. After the update, restart your terminal and verify that both report to PostgreSQL 17:

      pg_dump --version
      pg_restore --version
      
  3. Install yb-voyager and its dependencies using the following command:

    brew install yb-voyager
    

    To install a specific version of yb-voyager, use the following command:

    brew install yb-voyager@<VERSION>
    
  4. Check that yb-voyager is installed using the following command:

    yb-voyager version
    

Dependencies

When installing YugabyteDB Voyager using Homebrew, the following dependencies are installed automatically as part of the formula.

  • yugabyte/tap/debezium@2.5.2-\<voyager_version\>
  • postgresql@17
  • sqlite
  • go@1.24 (build-time)

You can perform an airgapped installation on Docker.

Install yb-voyager using a Docker image in an airgapped environment using the following steps:

  1. From a machine connected to the internet, run the following commands to pull and save the latest yb-voyager docker image (Pull the version from docker.io):

    docker pull yugabytedb/yb-voyager
    docker save -o yb-voyager-image.tar yugabytedb/yb-voyager:latest
    gzip yb-voyager-image.tar
    
  2. Download the yb-voyager wrapper script on the same machine using the following command:

    wget -O ./yb-voyager https://software.yugabyte.com/yugabyte/yb-voyager/main/docker/yb-voyager-docker
    
  3. Copy the yb-voyager-image.tar.gz and yb-voyager files to the airgapped machine.

  4. Load the docker image using the following command:

    gunzip yb-voyager-image.tar.gz

Prerequisites

Before installing yb-voyager in Docker, ensure that you have the following:

  1. Docker runtime installed on your machine.
  2. Docker is configured to run without sudo (recommended). Refer to Manage Docker as a non-root user in the Docker documentation.

Install

Perform the following steps to install yb-voyager:

  1. Pull the docker image from YugabyteDB's docker hub (pull the version from docker.io) as follows:

    docker pull software.yugabyte.com/yugabytedb/yb-voyager
    
  2. Run yb-voyager using one of the following methods:

    Method 1: Use the Wrapper script

    1. Download the script to run yb-voyager using the docker image from yb-voyager's GitHub repository, and move it to your machine's bin directory using the following commands:

      wget -O ./yb-voyager https://raw.githubusercontent.com/yugabyte/yb-voyager/main/docker/yb-voyager-docker && \
      chmod +x ./yb-voyager && \
      sudo mv yb-voyager /usr/local/bin/yb-voyager
      
    2. Verify the installation:

      yb-voyager version
      

    Limitations:

    Method 2: Use the Container directly

    Run the container directly with volume mounts.

    1. Run the container with an interactive shell:

      docker run -it --rm \
        --network=host \
        -v /path/to/export-dir/on/host:/home/ubuntu/export-dir \
        yugabytedb/yb-voyager bash
      
    2. Once inside the container, run any yb-voyager command. For example, to verify the installation:

      yb-voyager version
      

      Mount directories

      Mount all directories that yb-voyager needs to access (export directory, configuration files, SSL certificates, and so on). On macOS, add --platform=linux/amd64 to the docker run command.

Perform the following steps to install yb-voyager using an installer script:

  1. Clone the yb-voyager repository.

    git clone https://github.com/yugabyte/yb-voyager.git
    
  2. Change the directory to yb-voyager/installer_scripts.

    cd yb-voyager/installer_scripts
    
  3. Install yb-voyager using the following script:

    ./install-yb-voyager
    

    To install a specific version of yb-voyager on your machine, use the following command:

    ./install-yb-voyager --version <VERSION>
    

    It is safe to execute the script multiple times. If the script fails, check the /tmp/install-yb-voyager.log file.

  4. The script generates a .yb-voyager.rc file in the home directory. Source the file to ensure that the environment variables are set using the following command:

    source ~/.yb-voyager.rc
    
  5. Check that yb-voyager is installed using the following command:

    yb-voyager version
    

Collect diagnostics

By default, yb-voyager captures a diagnostics report using the YugabyteDB diagnostics service that runs each time you use the yb-voyager command. If you don't want to send diagnostics when you run yb-voyager, set the --send-diagnostics flag to false.

Use configuration files

For convenience, you can define all the parameters required for running yb-voyager commands using a configuration file (v2025.6.2 or later). Configuration files are in YAML format, and templates are available. For more information, refer to Configuration file.
