Managed Metadata Service support
If you have an existing taxonomy in SharePoint Server 2013, the SharePoint Migration Tool can now migrate your content types and term stores to Office 365. Global term store migration requires global tenant admin permissions.
Web Parts Support, Site Navigation, and more…
The SharePoint Migration Tool has continuously improved to support more complex migration requirements. From a humble beginning of accelerating files migration to incremental improvements leading up to complete SharePoint 2013 site migrations. Now using the SharePoint Migration Tool you can migrate just about every element of SharePoint sites that you care most about including Web Parts, Pages, and site navigation!
