  2. Execute the installer with admin or root privileges

    Run the installer file with ‘Run as administrator‘, which prompts you to remove the currently installed components, excluding the database. Click ‘OK‘ to continue the process. Once you click ‘OK,’ the AirWatch Remote Management Uninstall Components window appears on your screen. Click ‘Next‘ to proceed with the uninstallation procedure.

    Important Note: Please do not uninstall the database as the old database is required to run the upgradation process.

  3. Install the new components of VMware Workspace ONE Assist

    Upon the completion of the old component uninstallation process, the AirWatch Remote Management Setup prompts you to install new versions of the same components. Click on ‘Next‘ to proceed with the installation.

    In the installation procedure, the window prompts you to choose the installation path. Please don’t change the default path that has been imported from the install.config file.

    Click on the ‘Install‘ button to begin the installation process.

  4. Choose the installation type

    Upon clicking on the ‘Install‘ button, the AirWatch screen is greeted with two types of installation types.

    1. Standard Installation (Basic)
    2. Advanced Installation (Custom)

    For more details about each installation method, please refer to pages numbers 101, 102, and 103 of this document.

  5. Review configuration settings

    The settings are inhered from the install.config file. Please review the SQL server details, user names, Tenant FQDN, certificates, database configurations, communication network posts, and many other configuration settings.

  6. Install the components of VMware Workspace ONE Assist

    Once you are done with the verification of all the configuration settings, click the ‘Next‘ button, which eventually starts the upgradation process.

    Note: During the upgrade, the Installing Database process displays “Error Message: DBAlreadyExists.” This simply means it found the existing database and it has begun to upgrade it.

  7. Finish the installation

    After completion of the installation process, press ‘Next‘ button. This opens the finish wizard, where ensure that the ‘Execute Resource pack‘ check box is selected before you click the ‘Finish‘ button.
