Convert group messages to private channel


I noticed that Slack supports this feature:

Does Mattermost? If not, I’d like to recommend it. We have a group message that is taking on a life of its own. But how to move it to a channel and not lose the message history?

Hi @ptyler! Thank you for reaching out.

Here is a doc with more information on this:

Also, here is the CLI command tool that can be used:

From what I can tell this specific functionality does not exist in MM currently.

This is not a good implementation. Anyone should be able to convert DMs to private channels. I have to add someone to a chat and they will access to none of the history.

Please add the ability for anyone to convert DMs to private chats.

I’ll go look for a place to make feature requests.

I’ve added my votes to the request to retain message history when adding a new person to a DM. I would be happy with that feature OR converting DMs to private chats for everyone.

Adding users to group DM should provide an option to keep history

I came across this thread when looking for a way to convert group conversations to private channels. What started as a side conversation between four people on my team kind of met the need for having a new channel, but unfortunately, there is no way to do that. I would hate to just make the new channel and lose all of the chat history, so I would prefer to convert it.

Please add this feature.

Hi, everyone.

Please share your thoughts on the importance of having this feature there. Thanks.

Did anything happen in this matter? Slack has it for more than 2 years and it seems like a standard

Hello! This is already May 8, 2020 and the conversation stopped on Sep '19. Has this feature been implemented? I am in the same situation, trying to add a new member to a conversation…

Hi MM Team,

Any update on a way to convert group message to private/public channel?

Hello, everyone.

As we can see from the topic shared earlier, this feature is still being considered by the dev / engineering team as I believe that they are focusing on other critical bug fixes and feature implementations.

Please continue to keep an eye on it for now. Thanks.

Yes, I would also like to see this feature.


So 14 months later from the last message on this still no feature?
