well would upgrading to 3 be a pain in the you know where?
No shouldn't be a pain in the you know where, its pretty easy. Also you can installl new version without destroying your old boards, so if it dosen't work then you can keep on using the forums you have. The security level is much higher for 3 especialy after the first few patches. They spent a long time in RC release to make sure everyhting would work smootly. Because your forums are not modded to a great extent this should be a very easy change over for MP4Nation.
The new install feautre of phpBB3 will have a convert tab. You should install phpBB3 in a different folder, and the conversion will not change your original phpBB2 files or database.
PHPBB documentation wrote:
The upgrade process from 2.0.x to 3.0.x is a straight-forward, simplified process.
The process is in the form of a PHP file, similar to the update file found in phpBB 2.0.x. The file will take you through wizard-like screens until your phpBB is running 3.0.x.
Warning: Be sure to backup both the database and the files before attempting to upgrade.
Their is documentation help in the zip download of phpBB3 that is very easy to follow. You do not have to download anything special. THe converstion php file is located in the regular phpBB3 download. Here is what it says about the convertion process:

Note that the conversion requires CREATE and DROP privileges for the phpBB3's database user account.
To begin the conversion visit the install folder of your phpBB3 installation (the same as you have done for installing). Now you will see a new tab Convert. Click this tab.
As with install the conversion is automated. Your previous 2.0.x database tables will not be changed as well as the original 2.0.x files remaining unaltered. The conversion is actually only filling your phpBB3 database tables and copying additional data over to your phpBB3 installation. This has the benefit that if something goes wrong you are able to either re-run the conversion or continue a conversion, while your old board is still accessible. We really recommend you disable your old installation while converting, else you may have inconsistent data after the conversion.
Please note that this conversion process may take quite some time and depending on your hosting provider this may result in it failing (due to web server or other timeout issues). If this is the case you should ask your provider if they are willing to allow the convert script to temporarily exceed their limits (be nice and they will probably be quite helpful).
Once completed your board should be immediately available. If you encountered errors you should report the problems to our bug tracker or seek help via our forums (see README for details).
Looks as easy as pie. I will be doing this on my boards this weekend as a test. If you want I will report back to you on any issues I might have run into or weather its as easy as it sounds.
