Since we’ve already been providing a Microsoft SharePoint Online importer for several years now, you may ask yourself, why we decided to develop another one? And what does this “batch” mean?
The main reason to develop a new importer for SPO was the performance of our existing importer. The existing importer is using the SharePoint REST API for creating and uploading the documents to SharePoint Online, which is a rather slow method, especially when the target is a cloud system.
Microsoft has recognized this and therefore published the SharePoint Import Migration API. This API allows to bulk import many documents with few API calls. In addition, the documents to be imported are divided into batches that can be imported in parallel.
With our new Microsoft SharePoint Online batch importer, we want to allow our customers to migrate large amounts of data to SPO as quickly as possible. Since the new importer divides the documents into batches, we named it SharePoint Online batch importer to distinguish it from the existing Microsoft SharePoint Online importer.
