I'm attempting to convert a forum from vBulletin 3.0.1 to the latest version of phpBB. The forum is pretty well-established and has a lot of posts (the vBulletin post table is 28MB), and this seems to be causing difficulties in the conversion process.
Basically it gets through the initial checks and starts in on the conversion process, but times out partway through converting the database. This happens even when I'm performing the conversion locally on my own machine (using a mockup of the old and new forums and databases on EasyPHP, as described in the Offline Conversion knowledgebase article). The postindex table has been cleared out as well, just on the off-chance that'd help.
Is there any way to break the conversion down into smaller, more manageable chunks? Or might there be something else that's causing the converter to time out? Anything obvious I might've missed?
EDIT: Just tried running the conversion again after following the advice in
this post, and can confirm that it's choking on the post table - it got to step 7 of 16, last step shown was converting the post table, then it time out again.
