phpBB Private Messages -> Vanilla tool?
First, apologies if this is the wrong place to post this question, but considering I'll need to develop something if a tool doesn't exist, I wanted to check here first.
I'm in the process of testing a move from phpBB to Vanilla with a large forum of around 25 million posts. With a few modifications, Porter has done a great job of creating the main export file. I was surprised to see that private messages don't appear to be addressed by Porter (unless I'm missing something). I have around 1 million of those.
So my question is: does a phpBB private message exporter exist? If not, would it be most sensible to extend Porter with the functionality I need?
