Move 2 PHPBB forums + MySQL databases to a different hosting provider

Dear programmer, 1) I have to transfer two PHPBB internet forums from two different hosting providers to one new hosting provider. 2) One of the two forums was designed exclusively for Internet Explorer (some seven years ago). I would like it to work on Chrome/Firefox as well I have tried moving the first forum myself (I copied all the PHP files and exported + imported the MySQL database), but it won't work. It throws several errors. I think they are related to different paths on the before and after server, but I don't want to mess things up, so I want to hire someone to do it for me. The first forum is inactive, so you can "practice" with it until you get it right. The second one is active, so we have to pick a time frame in which to bring it down and transfer it, so the users can use it as soon as possible after transferring. Access to all hosting providers is via FTP and access to all MySQL databases is via PHPMyAdmin. You: 1) know PHP 2) know PHPBB 3) know MySQL This is not an urgent job. I also don't think it's very difficult, so I would like to give someone without any ranking on this site a chance to get some points. I usually get a HUGE response for simple jobs like this, so I'm sorry if I won't be able to react to all your responses/bids personally.
