Move content to another channel
Zulip makes it possible to move messages, or an entire topic, to another channel.
Organizations can configure which
roles have permission to move messages between
channels.
To help others find moved content, you can have the notification
bot send automated notices to the source topic, the
destination topic, or both. These notices include:
- A link to the source or destination topic.
- How many messages were moved, or whether the whole topic was moved.
- Who moved the content.
Move a topic to another channel
To move a topic, you must have access to both the source and
destination channels.

Moving content to private channels
Access to messages moved to another channel will immediately be controlled by the
access policies for the destination channel. Content moved to a private channel will
thus appear to be deleted to users who are not subscribers of the destination channel.
Content moved to a private channel with protected
history will only be accessible to
users who both:
- Were subscribed to the original channel when the content was sent.
- Are subscribed to the destination channel when the content is moved.
Moving content out of private channels
In private channels with protected
history, Zulip determines whether
to treat the entire topic as moved using the access permissions of the user
requesting the topic move. This means that the automated notices sent by the
notification bot will report that the entire topic was moved if the requesting
user moved every message in the topic that they can access, regardless of
whether older messages exist that they cannot access.
Similarly, muted topics will be migrated to the
new channel and topic if the requesting user moved every message in the
topic that they can access.
This model ensures that the topic editing feature cannot be abused to
determine any information about the existence of messages or topics
that one does not have permission to access.
