How do I bulk change the domain name in migration account email addresses?
There are two ways you can bulk update the domain name in the email addresses of migration mailbox accounts:
Use the Change Domains button
MigrationWiz now provides the option of doing a bulk update of email addresses on both the source and destination computers, where the change is of the address domain. The image below shows the Change Domains button.
When you click on the Change Domains button, the following box opens to allow you to bulk change the domain associated with mailboxes on the source or destination.
Use the BitTitan SDK PowerShell script
If the BitTitan SDK is not installed on your computer, the first step will be to download and install it. Our SDK will include the PowerShell and the Management Console modules. Click here to see the system requirements and download the SDK.
Before using the BitTitan PowerShell, make sure that all prerequisites have been installed, such as .Net 4.6.1 and PowerShell 4.0. PowerShell needs to be enabled on your MigrationWiz account. If API access is not enabled for your account, contact Support for assistance.
Why might it be necessary to change the Source or Destination address of all your users on a MigrationWiz Project?
If you are performing a tenant to tenant migration while keeping the same domain name, and you started the migration using the vanity domain on the Source addresses. Note: In the migration guide for this scenario, we recommend using .onmicrosoft.com addresses for both Source and Destination addresses to avoid this.
If you just ran Autodiscover on MigrationWiz to discover all your Source mailboxes, and you are migrating into a different Destination email domain.
These examples are two among others that might make it necessary to have to change those addresses. The script below will change all Destination addresses, based on a CSV file, that needs two columns, as shown below:
Once you run the script, the first thing it will do is prompt you to enter your MigrationWiz credentials:
After inserting your credentials, the script will prompt you to enter the MigrationWiz project name, and the location of your CSV file:
Once all the data is inserted, the script runs, and changes all the Destination addresses, as per the information in your CSV file.
