This article explains how metadata are migrated when migrating from Google Drive, OneDrive, Google Sites, or SharePoint to OneDrive or SharePoint.
During a file migration from Google Drive or OneDrive to OneDrive or to SharePoint libraries, metadata are migrated by default. This also applies to site migrations from Google Sites or SharePoint to SharePoint Online.
For any file or folder migrated, the default value for the Author and Editor is the migration account defined in the target connector. The Created and Modified metadata fields are set to the date and time of migration.
If you prefer to preserve the original, pre-migration values, you should use a Mapping table. If you already used a file or mail migration, users were added automatically thereafter their creation.
The migration list is used as a mapping table to migrate Metadata when the source and target emails are different. You can also add entries without assigning licenses in order to map users who you don’t plan to migrate. If an entry is missing, the individual metadata will not be migrated. Therefore, the mapping table must be complete from the beginning of the migration (even during the trial if wish to evaluate this functionality).
If the user is configured in the mapping table, the metadata are migrated with the following values:
- Author => email of the author of the file
- Editor=> email of the last user that modified this file
- Created=> date & time of the creation of the file
- Modified => date & time of the last time this file was modified
