What does Preprocessing do?
- It provisions the OneDrive accounts for the users.
- It sets the permissions to the migration account.
OneDrive provisioning in details:
The Cloudiway platform sends a request to Microsoft to provision the drives for 200 users at a time.
The request is asynchronous. Microsoft does not process it in real-time. Sometimes, the request does not get processed by Microsoft and the provisioning fails.
Permissions settings in details:
The Cloudiway platform tries to connect to the target tenant and to set the permissions of the Migration Account (The account used in your target connector) as a Site Collection Admin of the user’s personal OneDrive.
Troubleshooting Preprocessing issues:
- Verify that the target Address entered in the cloudiway user list matches the address defined in Sharepoint.
From the SharePoint admin center, click on User Profiles, then Manage User Profiles.
In the search bar, enter the username that you are looking for.
Verify that the email address matches the address in the Cloudiway User List
- If it matches, In the Office 365 admin center, verify that the user has a license that gives access to OneDrive.
- If the above are correct and if after several attempts the provisioning of the OneDrives is still failing, please do it yourself manually by following the PowerShell scripts that you can find in the article: https://docs.microsoft.com/en-us/onedrive/pre-provision-accounts
The Cloudiway platform uses the AppId/AppSecret provided in your OneDrive connector to set the permissions to the migration account. If this task is failing, most likely the AppId/AppSecret you provided in your connector is incorrect. If you’re still having trouble setting the permissions to the migration account, you can do it manually by following this article: https://help.cloudiway.com/article/permissions-admin-account-onedrive/
