This functionality exists in the SharePoint on premises product, and we need the same functionality to migrate an existing form to SharePoint Online. The form needs access to our customer data and this dataset is too large to keep in a SharePoint list. We also need to be able to use the Nintex Gateway to create the connection as this database is inside our corporate network. In order to migrate from one environment to another, there needs to be feature parity.
Thank you very much for posting your feedback for our review. At this time, we will not be adding this request to the near-term backlog, as we are focused on other highly requested features. However, we reevaluate requests every quarter and will reach out if priorities change. Please keep the feedback coming as it is critical for our longer-term planning.
