Background:
There's not yet any direct migration from phpBB to WPforo. A two-step process is possible, from phpBB to bbPress to WPforo, but it's uncertain how well that will work. In particular, some important forum post images are hosted directly on the site (esp. in Chris Hall's posts). The simpler migration tools only deal with thread/post text content, but not the forum-hosted media files. Two jumps just means more chances for stuff to go wrong.
I have some work items:
- Dig into the setup requirements and likely quality of the two-step migration process. Are there any reports of success using this migration path, or is it only a theoretical option?
- Identify alternate standalone forum software with a good phpBB migration story. I already have candidates from earlier research; this will be a slightly more in-depth triage round. (Just how good is the phpBB migration? What's site administration like? Any good/bad/missing forum features? etc.)
- Work out what hosting would cost for #2.
