Domino Exporter Pro is the next generation of the product previously known as Notes XML Exporter, a product that was first developed in 2009. The current version, 2019.1 was released in the spring of 2019, and it introduced additional capabilities like the ability to export multiple databases in one folder, as well as recursive exports of databases in a folder structure.
The software is licensed by Domino Domain, and priced by the number of documents that will be exported.
The Unlimited version has no limit to the number of document that can be exported. In addition, the buyer also gets up to three (3) hours of free customization/development of the tool, as well as a discounted hourly rate after that, if more customization is needed.
