Why does my Document Migration keep failing with Office 365 Small Business Tenant?
MigrationWiz will support Document Migration, but the Destination has to be configured in the following manner:
While the Source (e.g., Google Drive) is able to use admin credentials, the Destination, Office 365 Small Business Tenant, needs to be configured with the end user credentials. If admin credentials are used, the following error will surface:
Your migration failed checking destination credentials. OneDrive for Business administrative authentication failed with <your tenant URL>.
Referencing the Knowledge Base article associated with the error (https://bittitan.zendesk.com/hc/de/articles/115008257248), the following explanation is provided:
"We use SharePoint administrator API in order to perform auto-provisioning and provide rights to the administrator to access user sites. Some Office 365 plans prevent us from accessing them (Small Business, for example). If your plan doesn't provide access to the SharePoint administrator API, you must use end user credentials."
This means the MigrationWiz Destination needs to be configured with end user credentials.
