Hi, I’m converting users, post, topics etc from Mybb database to Discourse: [Migrate a MyBB forum to Discourse](https://meta.discourse.org/t/importing-mybb-to-discourse/130789)

I have followed also this guide: [Beginners Guide to Install Discourse on Ubuntu for Development](https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-ubuntu-for-development/14727)

In this way I have 2 instances of Discourse, right? One is for development (no docker) and then I’ll install production version (docker).

but `http://localhost:3000/` or `http://forum.omaggieconcorsi.com:3000/` don’t work (development version)

Anyway, the program is converting something from Mybb, but I don’t know where I can then export the data.  
Discourse I can’t see it with `http://forum.omaggieconcorsi.com:3000/` or `http://localhost:3000/` so how can I at least export the database with posts, users etc. from the old Mybb forum and then import it on new Discourse instance?

I can install only normal production version of Discourse without problems, but how can I do to import users, posts and topics I have converted from Mybb?

Thank you in advance!  
Deb

See [Importing MyBB to Discourse](https://meta.discourse.org/t/importing-mybb-to-discourse/130789) for how to import your mybb data to Discourse.

If `http://localhost:3000/` doesn’t work then you have a problem with your development installation but there’s no way to guess what the problem might be (did you install it? Did you start it up?).
