We are undergoing a migration from GitHub enterprise to Mendix private cloud. We are in the process of migrating our issues/stories and will make heavy use of the Epics-API. Upon building a POC we noticed that it isn't possible to move over comments, rather just issues/stories. Moreover, if an issue contains a document (e.g. pdf, json, png, jpg etc.) we have no way of moving this across. It would be greatly beneficial for us to have the available APIs extended to support these features as I'm sure this is a standard from all companies managing software.
