Possibly, we add importer features as we have paying business hosted customers to migrate – and we always open source those changes!
Good to hear that! Thanks, Jeff!
Just asking: any paying businesses migrating from MyBB right now? 
Is there a guide for that right now?
It doesn’t look like it. It works like most of them, though, and I recently added code that allows you to configure most everything in environment variables (as well as support permalinks). You’ll need to add the mysql2 gem (and virtually every guide includes how to do that).
How i use import script? Our Mybb forum and Discourse is not on the same server. I think I could create Mybb database backup and run import script?
The usual method is to install a development environment, copy the database to the development server and run the script.
You might use this howto as an example:
Rather than configuring the script as that example suggests, just run it and it’ll tell you what environment variables to set.
I’ve problem in that step (I think its about bundle install):
RAILS_ENV=production ruby script/import_scripts/mybb.rb
After that command here is the error:

discourse@vps-app:/var/www/discourse/script/import_scripts$Hello,
nobody can help me ?
Regards,
Try running the script from /var/www/discourse and not the script directory?
Thank you for your reply
so I have to copy past the mybb.ruby to /var/www/discourse before ?
I copy past mybb.rb in /var/www/discourse
but I have another issue
root@vps-app:/var/www/discourse# RAILS_ENV=production bundle exec ruby mybb.rb
Traceback (most recent call last):
1: from mybb.rb:1:in `<main>'
mybb.rb:1:in `require': cannot load such file -- mysql2 (LoadError)
root@vps-app:/var/www/discourse#You’ll need to install the gem. There are some howto posts for other importers that you should use as a model. You should read those. There are dozens more tiny little things you’ll need to figure out.
If you need so by step help and have a budget my context info is in my profile.
各位，
有人成功从 mybb 迁移到 discourse 吗？
我遇到了这个问题：

完全不知道如何修复这个问题。
尝试运行 RAILS_ENV=production rails runner mybb.rb
感谢您的回答，但我现在遇到了这个问题：
/usr/local/lib/ruby/gems/2.6.0/gems/activerecord-6.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:50:in ‘rescue in postgresql_connection': **FATAL: Peer authentication failed for user "discourse" (** **ActiveRecord::NoDatabaseError** **)**
切换到 discourse 用户后，我收到以下提示：
请指定有效的 Ruby 命令或要运行的脚本路径。
运行 'rails runner -h' 以获取帮助。
未定义局部变量或方法 `mybb' for main:Object
错误在于你的 Rails 无法连接到 PostgreSQL 数据库。我建议调查一下为什么 discourse 用户无法做到这一点。
你好，
我想我已经解决了这个问题，我正在参考以下内容：
通过编辑这个文件：
- 编辑文件
/etc/postgresql/9.5/main/pg_hba.conf
更新：已运行，非常感谢！
抱歉 @eviltrout，想再请教一下，如何在关闭的同时保持迁移运行？
我忘了用 screen 来运行，现在可以取消并重新运行吗？
