The planning stage on Confluence migration for my org is underway. I have a question about the user-installed apps on our confluence server. In checking the status of each of these apps, 7 of the 14 are Atlassian - provided apps and are in the marketplace, and two additional are not in the marketplace at all (Team Calendars and the Analytics for Confluence Plugin). At this time, no cloud versions are available for any of them. I understand that some may be folded into Confluence as a feature and others may be replaced by new apps? Since this is a key part of migration, how can I find out what Atlassian plans for these apps and plugins?
