    To stop an automatic 32-bit to 64-bit migration of Microsoft 365 Apps, do not use the MigrateArch="TRUE" setting in the Office Deployment Tool configuration.

    If a deployment is already configured to migrate architecture, remove that setting from the configuration.xml used for deployment.

    A migration is triggered when the Office Deployment Tool is run with a configuration like this:

    <Configuration>
  <Add OfficeClientEdition="64" MigrateArch="TRUE">
  </Add>
</Configuration>

    That setting uninstalls the 32-bit version and installs the 64-bit version.

    Key points:

    1. MigrateArch="TRUE" is the setting that performs the architecture change.
    2. If the target architecture is already installed, no migration occurs.
    3. The migration preserves existing products, languages, and deployment settings unless other changes are specified in the XML.
    4. The migration applies to Click-to-Run Office products with version 16.0 and requires Microsoft 365 Apps version 1902 or later.
    5. MSI-based Office installations can't be migrated with MigrateArch.

    If the goal is to keep devices on 32-bit Office, keep deployments configured for 32-bit and avoid any Office Deployment Tool package or update workflow that includes OfficeClientEdition="64" together with MigrateArch="TRUE".
