When I export a space to XML and import that space into another Confluence instance, the gliffy macros end up showing a "Gliffy Macro Error".
Both instances are Confluence Server 5.9.4 with Gliffy Add-on 6.9.1.
The page attachments show a file with the correct name that is referenced by the Gliffy macro configuration. Using the "Edit" link there yields an error in the Gliffy editor that says "The file was not able to load because it was not recognized as a valid Gliffy file. [...]"
We have moved several spaces with more than 200 Gliffy diagrams. Is there a bulk way to fix the display of those diagrams?
