Converting Existing Forum
 

I'm thinking of converting my forum from phpbb3 -> vB 4.0.

The forum is small:
Total posts 2059
Total topics 344
Total Attachments 318
Total members 108

If I were to make the change, I'd rather do it now before it got larger.

Can I transfer the data from my existing mySQL database for phpBB3 to vB4.0 (any issues)?
Are there any additional costs other than the intital 4.0 Publishing Suite price.
