Gliffy diagras offer the possibility to embed a "copy" of a diagram in another page. ( on a diagram in a page, click on "embed" the select confluence and then copy the proposed url
then in another page, use "insert images from the web" to add embed the image.
url look like https://confluence.example.com/rest/gliffy/1.0/embeddedDiagrams/3847b20f-e6e0-43af-878c-1b6115d62d33.png?utm_medium=live&utm_source=confluence
We are heavily relying on this in our self-hosted confluence.
Of course, after a migration to confluence cloud, those url pointing to the old instance are not migrated /updated.
Moreover we have 2 more blocking points
* how can you search for these links and find out each and every link we need to manualy update?
* the similar feature is gliffy diagrams in confluence cloud seams not to work: afec trying to embed a diagram, nothing is copied on the clipboard.
