Sharegate has released a new version of its SharePoint Migration Tools which supports Import & Export to Excel before migrating. 

Users will now also have the possibility to:

- massively edit all list item and document properties using Excel;

- take advantage of Excel’s effective and powerful formulas to enrich metadata;

- assign metadata to documents and content coming from a file system;

- divide the migration project by sending out the excel sheets and migrate by phases, only when ready; and

- have someone that knows the content update the sheets without having to install Sharegate.

The release also includes the ability to save PDF properties as SharePoint metadata and supports SharePoint custom field types.
