Though this document (https://support.atlassian.com/migration/docs/how-groups-and-permissions-are-migrated/) is fairly complete regarding how users and groups are migrated from server to cloud for both Jira and Confluence. However, it does not cover what happens when Nested Groups are in play.
Is there any real documentation on what needs to be done before or after so that migrating users and groups with nesting to cloud that works in the end?
