We had our old forum running on phpBB and our new one on XenForo. Our old forum script and database were heavily customised. The standard conversion of the phpBB database and its merger with the existing new Xenforo database seemed to be impossible.
gConverter.com team made it happen in a professional and manner.
Good communication throughout the process should be noted.
Right to the point, clean work. We honestly and highly recommend gConverter.com team.
