Note : We recommend to always test the mass import on a mirrored test instance first. Also, Confluence must be re-indexed prior to performing the import so all diagrams are found.

If you want to convert multiple Gliffy diagrams in your Confluence instance to diagrams, you can use the mass import function. This is useful when upgrading from Gliffy to All diagrams created with Gliffy in JSON format can be quickly and easily imported into, and edited as native diagrams.

Firstly, install the app in the marketplace administration section of Confluence. After it's installed, in the administration section you'll see "Add-on Configuration" under "DRAW.IO ADD-ON" in the left-hand side navigation:

Once in the configuration page click the "Diagram Import" tab. There you're offered the option to display all Gliffy diagrams, or start the import process:

The import might take some time, depending on the number of Gliffy diagrams and server specifications. Once finished a text report of the import is created, you can download and inspect the results:


When is it best to perform the import?

It is better to perform the conversion outside of your company's normal usage hours of the Confluence instance. It is possible during normal working time, but it's best to carry out the whole operation whilst the minimum number of changes are being made to the relevant pages.

Backup automatically creates a new page revision of every page with a Gliffy diagram. You can always revert pages to their previous versions if needed, no Gliffy data is deleted.

Uninstalling Gliffy

When you buy an app, like Gliffy, you get a perpetual license to any version if the release date is prior to your maintenance period ending. Those versions will continue to work beyond the expiry of maintenance, both for viewing and editing. That said, most Confluence admins prefer to clearly recommend and so uninstall the Gliffy app. If Gliffy is already uninstalled, the mass Gliffy to import will still work.


If you encounter any issues during mass Gliffy import, please email sending the text of the import report as an attachment.
