Create Migration Mappings
After creating an Exchange On-Premises migration project, create migration mappings to define the source and destination mailboxes.
You have two ways to create mappings for a project.
- You can create mappings directly after creating the project using any of the following methods.
- Add mappings
- Import mappings
- You can also click **Projects** in the left pane to access the **Projects** page, and click the project name of the project for which you want to create mappings.
On the **Project mappings** page, you can directly click **Create mapping** to add mappings one by one or import mappings in bulk.
Add mappings:
To manually add mappings, refer to the following steps:
-
Click Add on the Add/Import mapping page.
-
Enter the source and destination email addresses you want to migrate from/to.
-
Select the source and destination types from the drop-down lists.
-
Click Save to save the new mapping.
Repeat the steps above to add additional mappings.
If there are mappings that already exist in another project, the Alert panel will appear. You can select to remove duplicate mappings from the current project, or move duplicate mappings found in other projects to the current project. Then, click Save to save the updates.
Import mappings:
To import mappings in bulk by importing a configured Excel file, refer to the following steps:
-
Click Import on the Add/Import mapping page.
-
In the Import panel, you can download the template for mapping examples and configure mappings directly in the file; or you can click Export on the Add/Import mapping page to export a mapping file and modify it.
-
In the Excel file, configure the information of each mapping in one row, and save the file. You can refer to the screenshot and table below for how to configure the mappings.
| Column | Value |
|---|
| Source | The email address of the source mailbox. |
| Source type | The supported type of the source mailbox● Archive mailbox● Resource mailbox● Shared mailbox● User mailbox*Note: If the source mailbox is a linked mailbox, select User mailbox in the Source type column. |
| Destination | The email address of the destination mailbox. |
| Destination type | The supported destination type of the source mailbox● Archive mailbox● Microsoft 365 Group mailbox● Resource mailbox● Shared mailbox● User mailbox*Note: If the destination mailbox is a linked mailbox, select User mailbox in the Destination type column. |
> ***Note**: We do not recommend that you configure more than 10000 mappings in one project.
4. After the configurations, import the mapping file by dragging the file or browsing the file from the local location. Click Save to save the mapping file to the project.
- Click Save after you finish adding mappings to the project.
