Install the latest version of BPMN Modeler Enterprise (>= 3.18.0-ENTERPRISE)
In case you are using the BPMN Modeler Free, get the free trial version of BPMN Modeler Enterprise at no cost (https://marketplace.atlassian.com/apps/1219284/bpmn-modeler-enterprise?tab=overview&hosting=server )
BPMN Modeler Free and Enterprise versions can be installed in parallel. So uninstalling your BPMN Modeler Free beforehand is not required
As Confluence administrator, perform the Upgrade procedure to make sure all of your diagrams are upgraded to ENTERPRISE, as described here: Features for Confluence Admins
We recommend doing this even if you are already using BPMN Modeler Enterprise. Maybe some old FREE diagrams are hiding somewhere from earlier days!
After completing the upgrade procedure, it is necessary to perform a Re-Indexing of your Confluence pages
After Re-Indexing completion, verify that there do not exist any more FREE diagrams in your Confluence by performing the Analysis again
Done. You may now continue to migrate your pages to Confluence Cloud. All ENTERPRISE diagrams (page macros) will be recognized seamlessly after installing the BPMN Modeler Enterprise Cloud app.
