The IONET Notes Pipeliner allows you to select entire Notes Databases - or specific data only - then export it to
SharePoint,
Box,
Google G Suite/Drive, XML, PDF or PDF/A.
Automatically recreate Notes Views, Embedded Views, Form UI, ACL Security, Rich Text, Sections, Graphics, Doclinks, Attachments, Embedded Objects, Quickr Forms and Response Hierarchies, resulting in a familiar experience for End Users.
Use Delta Exporting to migrate the majority of your data in advance, then complete the process over a single weekend, migrating up to 10 Databases simultaneously, and in recent projects, over 50 million documents.
And if you're migrating to SharePoint or Box, create Metadata from each Notes document using fields and @formulas, to keep using Notes data in your new environment.
