The option ‘Include Document Metadata’ has been added to Microsoft Office 365 destination Advanced Settings. By default, this setting is turned off and must be turned on to migrate custom SharePoint / OneDrive document metadata.
When performing a site migration, the default "Title" and "Description" metadata columns will always be migrated, along with the "Created", "Modified", "Author" and "Editor" fields. By turning on the ‘Include Document Metadata’ setting, further custom metadata columns will be included in the migration, subject to the following restrictions:
Supported custom metadata types:
- Single line text
- Multi line text
- Number
- YesNo
- DateTime
Columns of the supported types will migrate both the column name and description, as well as the associated document data. All other column settings, such as "Default Value" and "Enforce Unique Values" will be set to their default values. Migration of these settings are not currently supported.
Default Views
All migrated custom metadata will default to hidden in the SharePoint/OneDrive UI. In order to see the columns and the associated metadata, the migrated columns must be added to a view within the SharePoint UI (this can be done by selecting the show/hide column option from an existing columns dropdown).
API Support
Site metadata is only supported when migrating using the default API settings for the source and destination in Migrate, specifically:
- Microsoft CSOM API for exporting site metadata
- SharePoint Migration API for importing site metadata
How we capture this information?
Each custom metadata column that is migrated will be counted as a ‘SiteMetadata’ migration item. These are recorded alongside the document migration statistics and each migrated column is counted and displayed in the migration summary.
