Migrating Backup Data

This section describes how to migrate your backup data from a Microsoft Azure object storage repository configured in Veeam Backup for Microsoft 365 to Veeam Data Cloud.

To migrate your Veeam Backup for Microsoft 365 data to Veeam Data Cloud, complete the following steps:

1. On the Veeam Backup for Microsoft 365 server, click the Veeam Migration for Microsoft 365 icon on the Microsoft Windows desktop to launch the migration tool.
2. On the migration wizard welcome page, click Start.

At this step, you can also specify the migration settings. For more information, see Specifying Migration Settings.

3. At the Source Configuration step of the wizard, specify settings to connect to the PostgreSQL instance. The PostgreSQL instance contains the configuration database of the Veeam Backup for Microsoft 365 server used to create backup whose data you want to migrate to Veeam Data Cloud:

1. From the PostgreSQL Version drop-down list, select the version of the PostgreSQL database system that runs the Veeam Backup for Microsoft 365 configuration database: 15 (if the product uses PostgreSQL version 15.9) or 16 (if the product uses PostgreSQL version 16.4). For information on the PostgreSQL versions supported in the product, see the System Requirements section in the Veeam Backup for Microsoft 365 User Guide.
2. In the Database Hostname field, specify the domain name or IP address of the server where the PostgreSQL instance with the Veeam Backup for Microsoft 365 configuration database resides.
3. In the Database Port field, specify the port number of the Veeam Backup for Microsoft 365 PostgreSQL instance.
4. In the Database Username field, specify the user name of the database user account to connect to the PostgreSQL instance.
5. In the Database Password field, specify the password of the database user account to connect to the PostgreSQL instance.

4. At the next step of the wizard, specify settings of the source backup repository from which you want to migrate backup data to Veeam Data Cloud:

1. From the Client Type drop-down list, select the type of object storage repository that contains the backup data you want to migrate: Azure.
2. From the Client Repository drop-down list, select the necessary object storage repository. The list contains object storage repositories of the selected type added on the Veeam Backup for Microsoft 365 server.

3. Click Validate. The migration tool will check whether the source object storage repository meets the requirements. For information on what backup repositories are supported for migration, see Considerations and Limitations.
4. Once the validation check is completed, click Next.

5. At the next step of the wizard, do the following:

1. In the Client Blob Container SAS Url field, specify the SAS URL used to access the source Azure Blob object storage repository. You must generate the SAS URL for the source container in advance, before starting the migration process. For information on how to do this, see Microsoft Learn.

The SAS URL must meet the following requirements:

• The SAS URL must have the Read and List permissions.
• The SAS URL must be valid for the time required to complete the migration process. This time depends on the size of the backup data and the location of the datacenters where the source backup repository and target Veeam Data Cloud reside.

2. In the Client Name field, check the name of the backup repository. The value in this field is populated automatically. The migration tool will also automatically populate values in the Client Container and Client Folder fields that define the location of the migrated data in the source backup repository.
3. Click Next.

6. At the Target Configuration step of the wizard, specify the Migration API settings and start the migration process:

1. From the Migration API Endpoint drop-down list, select the migration API endpoint that you want to use, based on the region.
2. In the Migration API Key field, enter the API key that you obtained in Veeam Data Cloud for Microsoft 365. For more information, see Obtaining Migration API Key.
3. Click Begin Migration.

7. Wait for the migration process to complete. The time required for migration depends on the size of the backup data and the location of the datacenters where the source backup repository and target Veeam Data Cloud reside.

If you want to stop the process before it is completed, click Cancel Migration.

8. Once the migration process is completed, click Close to finish working with the migration tool.

After the migration process is completed, it takes 5 to 10 minutes to update the information about migrated backups in Veeam Data Cloud. Then, backups of your Microsoft 365 data become available in Veeam Data Cloud, and you can perform restore operations with these backups. Once you configure and start a backup policy, Veeam Data Cloud for Microsoft 365 will run an incremental backup session.

Repeat the migration procedure for all backup repositories that contain the data you want to migrate to Veeam Data Cloud.
