draw.io is the most powerful diagramming add-on for Confluence. It allows you to create and collaboratively develop graphs and diagrams of any kind, directly within Confluence pages: flow charts, network diagrams, organization charts, UML diagrams, mind maps and more. A second, mature add-on with similar features is Gliffy.
For customers who wish to upgrade from Gliffy to draw.io, or who want to run both add-ons temporarily or permanently,draw.io comes with a practical feature: Gliffy mass import. All diagrams created with Gliffy in JSON format can be quickly and easily imported into draw.io, and edited as if they were native draw.io diagrams.
2. import Gliffy diagrams
In the Add-on Configuration, select the “Diagram Import” tab.
Click on either the “Import all diagrams” button, or the “Import displayed diagrams” button.
3. Download report
Wait until the import has finished, and download the report. Use the report to see whether all diagrams were converted successfully, and which diagrams were not able to be imported.
