All I've tried so far is the default process:
Tools -> Import -> bbPress Standalone
I'm given a path to bb-config.php, at the root of my WordPress install, which seems to be correct. Going by these default settings has worked just fine on a much smaller test site. On this big one however, no such luck.

We have ~20'000 threads and ~15'000 users. If you've attempted to migrate a fairly large website to bbPress 2.0 from the legacy BuddyPress forum, kindly share your findings.

if you have some deeper knowledge in php, mysql and regular expression - you can use the phpbb3 converter and make some change to the code. The code of the phpbb3 converter is understandable - you only must change the tables and row to match the database structure of the Woltlab Burning Board. Its only the question of understanding ...

Is it a big issue to restart with a blank, fresh forum?

Do you not like the current software you have?

But I had to do a 3 step migration to do it: YetAnotherForum to vBulletin to phpBB to bbPress.

It's a tedious process, and not perfect, but I got the forums converted!

Basically, in all my research the only converter for YetAnotherForum.NET that I could find it vBulletin. So that's the first step. unfortunately it is commercial, and closed source, but a $100 is much cheaper than paying someone to convert it for you!

vBulletin has a tool called ImpEx that can import a YAF forum into vBulletin. But it is tricky since YAF uses MSSQL, and you want to convert to MySQL on vBulletin. I did all this on my local machine running Windows, with a MSSQL server to run the YAF database and WAMP to run vBulletin.

I did not have YAF installed locally and running, just the database. You probably want to get your YAF forums running on a local Windows machine as a first step. The YAF to vBulletin importer is old and totally unsupported, so it is crude, but better than nothing. I was only able to import about 80% of my forum content, and I lost a user account. But one user out of 600 seemed a small price to pay.

I think the loses were due to funky characters and long titles, so if you have a local install of YAF, you can fix those things before you import.

After you get the data into vBulletin, it is a much smoother process. There is of course a lot of converters for phpBB, and converting from phpBB to bbPress is pretty easy.

In the end, the migration went ok, I had some issues with the HTML code in the posts, had to convert some characters in the database, and install some plugins so that the HTML content in the old posts would work in bbPress. But it was all worth it to get away from YAF, the forum members all seem to be happy with the new forum, no complaints, just a few feature requests.

I have really been meaning to do several blog posts explaining how to do all this cause it's one hell of a project, but who ever has the time to do everything they want to?

If anyone else takes the plunge and tries to migrate from YAF to bbPress and has any specific questions, let me know and I'd be happy to try and give a hand!

So yeah, uhh, anyone got a dump of a database for one of these? I don't even have a test install I can run ASP.NET that I know of...

Edit: Nevermind, Apache can do it. Will look into a conversion script, but it'll be written in PHP.

Thank you.

here are the queries I used. There are no explanations but maybe it will help you.

I made this by duplicating the tables fluxbb_forums,fluxbb_topics & fluxbb_posts in my bbPress database.

DON'T FORGET TO BACKUP BOTH TABLES BEFORE DOING ANYTHING !

For each table I deleted some fields and rename them to match bbpress structure, and at the end I import the datas in the right bbpress table.

Do the queries one at time so you can check if there are errors.

I didn't made anything on the users table as it's integrated with WP on my website.
To give back a WP user its fluxBB posts; do this

UPDATE bb_posts SET poster_id=NEW_WP_USERID WHERE poster_id=OLD_FLUXBB_USERID;
UPDATE bb_topics SET topic_poster=NEW_WP_USERID WHERE topic_poster=OLD_FLUXBB_USERID;

When done, don't forget to recount everything (posts, etc). in the admin panel.

Anyone else have any other wild ideas?

I figured if there was a way out of YAF, it would most likely be to phpBB. Surprised I didn't find this in my own searches.

If I can just get this data out of YAF, I think it will all be downhill from there :)

If you read the SMF to bbPress thread you'll see what machinations were needed. Good luck!

Recently I volunteered to move and fix an install of YetAnotherForum.NET, and after looking under the hood, I'd really like to scrap YAF and move it to just about any other forum software, especially a platform that could be migrated to bbPress.

Any mad scientists with wild ideas?

Is there any update on this, or newer script for importing phpbb2 ?

Here are a couple:

RE: public, private and superprivate forums:
http://bbpress.org/plugins/topic/hidden-forums/

That enables you to hide forums based on roles.

1) Can bbPress import my phpbb database? What info am I liable to lose?

2) My forum has a public section, a private section, and a superprivate section for admins and such. Does bbpress support this sort of thing? We govern who can go where with groups and permissions in phpbb, but I'm concerned that it wouldn't translate.

Thanks!
