Cloudiway’s mailbox migration tool has a distinct migration list to manage the migration of distribution lists between Office 365 Tenants. This migration tool can be used to identify distribution lists in the source tenant and populate the migration list, as well as provision distribution lists in the target.
The setup and usage of this tool are the same as provision shared or room and equipment mailboxes. If you have not already set up your project and tenants for a mailbox migration be sure to follow the mail migration admin guide prior to migrating distribution list: https://cloudiway.com/resources/documentation/microsoft-365-mail-migration/.
To use the distribution list migration list, open your migration project and navigate to the Mail Migration area. There you will see a Distribution list section. In this list, you can click on the Manage drop-down menu to populate the migration table with either a CSV import or by manually creating entries one at a time.
You can also select the Migration drop-down menu and use the Get List option to automatically detect distribution lists and populate the migration table. When using this option, you must specify the source and target connector and target distribution list email address format. Select the Matching Rule drop-down menu to choose from different email prefix rules, and then choose the target domain to set in the list. In Office 365 migrations you will use a matching rule other than “Mail Exact Match” and you will need to specify the target email domain name. This is because two Office 365 tenants cannot actively use the same domain name at the same time. You can also specify a prefix to be added to the target distribution lists.
Once your list is populated, if you want the Cloudiway tools to create the target distribution list you can select the items you want to provision and click on the Migration drop down menu and choose Pre-Processing.
