The data restoration process is handled by your specific backup software application. As many variables can affect your unique environment, Wasabi strongly recommends that you seek guidance from your backup software’s technical support team if you encounter difficulties or have application-specific inquiries. ## - ## Requirements - Veeam Backup for Microsoft 365 v7 or higher installed and licensed. This solution was tested with v7.1. - Active Microsoft 365 account with multi-factor authentication turned on. - Active AWS S3 cloud storage account. - A standard AWS S3 non-Object-Locked (OL) (non-immutable) bucket with access keys. - An active Veeam Backup for M365 repository with your M365 organization backed up to it. - Active Wasabi Cloud Storage account. - A Wasabi non-Object-Locked (OL) (non-immutable) bucket created with access keys. ## Wasabi Cloud Sync Manager (WCSM) is a paid migration service. Refer to [Getting Started With Wasabi Cloud Sync Manager](https://docs.wasabi.com/docs/wasabi-cloud-sync-manager-wcsm-getting-started) to begin the migration process. After your data has been migrated, verify that it is available in Wasabi by logging into the Wasabi Console, navigating to the bucket used to migrate Veeam Backups for Microsoft 365 from AWS S3 to Wasabi, and checking for data. Below is an example of a folder in a bucket used during testing. After the data has been fully migrated to Wasabi and verified, proceed with the next section. ## Navigate to the Organizations tab and select your organization. Select the existing backup job that backs up to AWS S3. Click **Delete** at the top. Click **Yes** when prompted to delete the selected job. ![](https://cdn.document360.io/bef0a1ea-7768-4d5a-b520-c4fe2f7fafad/Images/Documentation/image-1718642672545.png) ## 1.
