Acknowledged yes, adressed no.

Using dendrite at the time was a bet on the future : "use it now and you won't have to migrate".

You can also migrate by replicating messages, or mirroring new messages via a bridge.

In my opinion they tried nothing and they're all out of options.

I'm part of the sysadmin team who studied the migration paths for the Dendrite in question in this blog post and unfortunately as a volunteer it's hard to find the time to invent migration paths (even if we have the knowledge) and make it happen while there's also many other needs unaddressed elsewhere.

Given that you seem expert in the matter, would you like to help and own the migration? That'd be awesome!
