In Output mode, connectors push content and metadata. Many of them can also build version series’ from the source systems.
Versions
If a connector retrieves versions, they will be queued as a series in the order of oldest to youngest and the writing connection (if it supports versioning) will attempt to write them in that order. Some connectors, such as Box, and SharePoint REST, can be configured to roll back any documents in a version series, should any of the documents in the series fail to upload
