Moving from BBPress 2.0

edited July 2012 in Vanilla 2.0 - 2.8

I currently run a fairly large forum (9,000 users) on BBPress 2.0 and I am migrating over to Vanilla. I need to keep the users on Wordpress, for various things, but I am using SSO.

I am trying to import the old forum posts into Vanilla and I find myself perplexed. I found the exporter, but it only uses BBpress 1.0 -- I tried it for kicks and it just errors out, "no topics, no replies".

I think I could export the forum topics manually but I'm not sure how I'd go about importing them. Would I have to somehow automatically generate all of the existing users on Vanilla? Since they don't have a userID if they've never logged in, right?

I've spent a good three hours researching this tonight and I'm at a little lost. this is my last step and I'd really like to go forward. I don't mind getting my hands dirty but I need a little direction.

  • I'm in the same case, did you find a way to migrate from BBpress 2 ?

    @Shain It looks like BBpress 2 is a complete change from BBpress 1. I don't have an install available to test, but from some searches, it looks to share tables with a wordpress install. :(

    I have inspected a converter to migrate BBPress 1 data to version 2, and indeed there have been several changes. In best case, it would be a matter of replacing table names and fields (eventually splitting some data here and there to multiple tables). In worst case, a brand new library would have to be implemented. It's not the best of news, but it's not a trivial tasks (especially because it's crucial that data is imported correctly, a "more or less" result is not acceptable).

  • @businessadd‌ @hgtonight‌ Yes it looks like the tables are shared, I am trying to migrate my forums over and do not have a table called "bb_forums" which is why I'm getting error 1024 when using the vanilla porter.

    Has there been any additional insight gained since the last post back in March 2013?

    Sorry for the bump.

    you could try , if you don't solve it yourself or get other solutions...

    http://gconverters.com/start/

    or

    Skisma previously said: Can I migrate all existing forums/topics/users to vanilla once installed, or do I have to start fresh? This wouldn't be too big a deal if I cannot since the forums have only been open one week, but it would be ideal.

    If it were me I would start fresh, instead of converting, since it is only a week old. And you won't have to worry about any conversion issues that could arise.

    I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.

    I used the following to import Users, Categories, Discussions and Replies. My role mapping is simplified because that is all I needed, and I hardcoded a prefix in a meta key value. 'wp_user_level' maybe something else if you use a different prefix than 'wp_'. Also no private messages, because I left them in BuddyPress. But its a start. You need to insert this code into the vanilla2export.php file:

  • ^ The features array in the above code is inaccurate. It doesn't have PrivateMessages support and I doubt it successfully imports passwords either. I didn't need the passwords as I set up SSO with WordPress and jsconnect and jsconnect auto.

  • Thanks for sharing anyway, maybe someone can use this to build a full porter class.

  • @Bleistivt‌ They could do that. My motivation for pointing out the errors and limitations, was partly to help prevent disappointment on the part of users, and partly to provide other developers with the clues they need to complete the work. It is much better to have an almost complete bit of code than nothing at all. Especially when what needs doing is well documented. B)

  • Is there any progress on this project? I'm looking to do exactly this!
