For customers who want to switch from Gliffy to draw.io, the app comes with a practical feature: The Gliffy Mass Import (Confluence Server only). All diagrams created with Gliffy can be quickly and easily imported into native draw.io diagrams.
3 simple steps to mass import your Gliffy diagrams
1. Install the draw.io app
In the General configuration under "DRAW.IO ADD-ON" select "Add-on Configuration"
2. Import Gliffy diagrams
In the Add-on Configuration, select the "Gliffy Import" tab. Click on either the "Start Import" button to import all of the Gliffy diagrams in your instance, or use "Filter by spaces" to import only the diagrams attached to pages in this specific space.
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.
When should you perform the import?
We recommend that you do the conversion outside of normal usage hours of your Confluence instance. Even though it is possible to perform the conversion while employees are using your Confluence instance, it can significantly delay or extend the conversion process.
In addition we recommend you to first start the mass importer on a test-instance of confluence in order to reduce the risk of errors during the process.
What Confluence permissions are needed?
The administrator that triggers the Gliffy mass import must have write permission for every page that has a Gliffy diagram. Otherwise, the mass importer can't save the draw.io diagram to that page!
Pages with restricted permissions aren´t editable by the admin. That causes the mass importer to fail to convert Gliffy-Diagrams on restricted pages.
Will draw.io create a backup?
Yes, draw.io automatically creates a backup before the conversion of a diagram begins. You can always revert to a previous version using the version history of the Confluence page.
What happens if you uninstall Gliffy?
You can keep Gliffy in your Confluence instance, even after the support period has ended. Although Gliffy diagrams can then not be edited, they will be displayed as normal, and can also be converted to draw.io diagrams. If you uninstall Gliffy, draw.io can still perform the mass import, but the Gliffy diagrams will not be displayed within your Confluence instance.
