Microsoft has provided a new solution and easiest way to change the office 365 ProPlus architecture from 32-bit to 64-bit using the MigrateArch attribute.

Patch My PC

The change from an Office365 ProPlus from 32-bit to a 64-bit installation of Office 365 ProPlus is a bit easy.

The Office Deployment Tool and its configuration.xml file support an optional attribute named MigrateArch. If the MigrateArch attribute is set to True, then your installation of Office365 ProPlus can be changed.

NOTE 1– Previously, we had to uninstall the Office365 ProPlus 32-bit version and then install the Office365 ProPlus 64-bit office, which took so much time and configuration, which was, in the real world, not an easy task.

NOTE 2 – Check out the additional tips section at the bottom of this post to get more details about the issues with the MigrateArch attribute method.


PrerequisiteMigrateArch Attribute

  • Minimum Office 365 ProPlus 1902 version installed on the device you want to change the architecture using MigrateArch.
  • Office Deployment Tool minimum version of 16.0.11615.33602.
  • A shared location contains the source files for all the product (64 bit) and language files (French, German, etc..) for the architecture you are changing.
  • Configuration.xml, which will be used for the installation of the office365 ProPlus 64 bit version
  • Download.xml file, which will be used to download the Office365 ProPlus 64 bit version

NOTE 1 – In this post, we will install Office365 ProPlus 1902 SAC T and change the architecture of Office from 32-bit to 64-bit.

NOTE 2 – Before changing to a different Office365 ProPlus architecture, ensure that your existing add-ins, macros, and complex Office files work on the new 64-bit architecture.

Prepare Download.xml file

As a first step, you can prepare the download.xml file, which will be used to download the Office 365 Semi-annual Channel (Targeted).

Refer to my previous post to check and understand the process of changing office365 ProPlus channels.

  • Download the Office Deployment Tools, download from here download the link
  • After downloading the tool, run OfficeDeploymentTool.exe
  • Extract the files to drive on your computer
  • You can see Setup.exe and a couple of Configuration files
    • Configuration-Office2019Enterprise
    • Configuration-Office365-x64
    • Configuration-Office365-x32

Create a Download.xml file and copy this content.

  <Add SourcePath="\\ServerName\MS Office Deployment Tool" OfficeClientEdition="64" Channel="Targeted">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />

Prepare Configuration.xml file

  • Create a new Configuration.xml file. This file will be used for SCCM Office365 ProPlus 64-bit application deployment.
  • Open the Configuration.xml file and modify it to reflect the following
  <Add OfficeClientEdition="64" MigrateArch="TRUE" Channel="Targeted" AllowcdnFallback="TRUE">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
   <Display Level="None" AcceptEULA="TRUE" />  
  <Logging Level="Standard" Path="C:\Logs" /> 
  • In the first line of the above XML file (Add OfficeClientEdition=”64″ MigrateArch=”TRUE” Channel=”Targeted” AllowcdnFallback=”TRUE”), we are asking the script to migrate the Office365 ProPlus Architecture from 32-bit version to 64-bit.
  • Display Level “None” and AcceptEULA=True are used for silent installation.
  • Logging Level standard and path provided to store the installation log file.
  • Channel “Targeted” is used for the Semi-annual Channel (Targeted). If you want to download the monthly channel, replace it with Monthly.
