Looks like it’s behind an experimental flag, only applies to new rooms, and isn’t available on the public app.element.io instance right now (the Labs screenshot they showed doesn’t show the option on element.io+matrix.org when I checked just now):

For it to work, looks like it needs another in-progress feature to allow new members to decrypt previous messages (Matrix can’t do that yet???):

https://github.com/matrix-org/matrix-spec-proposals/pull/4268

(That one isn’t even in the spec yet, it’ll take a lonnnnnng time before we see any real movement on it, possibly a year or two. A year or two before you can see encrypted messages from before you joined a room. Insanity.)

A contributor calls this encrypted metadata feature a “partial prototype:”

https://github.com/element-hq/element-meta/issues/1214#issuecomment-3714132569

And that issue was opened in 2017. Pretty crazy they’ve been discussing this for nearly 10 years and it’s just now “a partial prototype,” but that’s Matrix for you.

So it was all of your messages?

Can you explain what bridge you used and how you got the whole history moved over?

Every messages in your server’s entire history, or just the channel layout?

I know the Mautrix bridge can create the channels for you, but their backfill feature was not designed for full archival, it can’t really do that.

Thank you!! Really looking forward to this, Movim is already pretty nice.

And I believe the devs are working on adding discord-like channels with multiple groups under a single community.

If you have a link to a discussion or issue where they’re tracking this, I’d love to follow it.

They’ll also need to figure out how to let rooms have more than 1000 people, which is currently the limit on Movim (and it might be an XMPP limitation). Right now, Matrix seems like the only option for a Discord migration, but I hope that changes soon.

I might move my Discord community to Matrix, but I’d want a full 100% clone of the server’s history. Seems like that’s almost possible?

Discord scrapers like DiscordChatExporter can dump a whole channel to JSON (although I don’t see a lot of scraper options that let you pause/resume/retry an export… looking for suggestions if people have any).

And the Mautrix Discord bridge already makes it look like real users sent bridged messages. I think with a little customization, the Mautrix bridge could be modified to import an enormous JSON file to fully mirror an entire Discord server, instead of just grabbing messages in real time. It’s already got the functions there to “send a message as xyz user.”

Matrix or not, “take your Discord dump and clone it somewhere federated” would be huge for migrations like this. I really hope someone works on that soon 🙏
