+
+From Mattermost v9.1, you can change the members of your group conversation by converting the group message to a private channel. When a group message is converted to private, its history and membership are preserved. Membership in a private channel remains as invitation only.
+
+<Note>
+
+- Any member of an existing group message, except [guests](/administration-guide/onboard/guest-accounts), can convert that group message to a private channel.
+- Conversation history will be visible to all channel members.
+- All group message participants must share at least one team membership.
