#11. Design the migration policy

A SharePoint migration policy allows you to configure the conflict resolution, filter policy, user mapping, column mapping, content type mapping, template mapping, URL mapping and other options for SharePoint Online Migration. Refer to   for details. 

*Note: To ensure the maximum preservation of source data, we recommend you use Merge as the container level conflict resolution and use Overwrite by last modified time as the content level conflict resolution.

*Note: If the file/item has more than 100 versions, it will take more time to migrate the data. Therefore, we recommend that you use the version filter policy to migrate no more than 100 versions. Refer to for details.
