How do i convert a Logic 4.7 file into a Logic 7.2?

Question

I've recorded an album with my old G4 using Logic Pro 4.7 and a Korg 1212 audio interface a few years back.
Now i've loaded it into my MacBook Pro using Logic Pro 7.2 and the MOTU Traveler. it opens the arrangement but obviously all plugins aren't working because i used the Korg 1212 interface before. Once i change to CoreAudio, all the plugins on that channel strip disappear. I realized that Logic uses AU now but how can i convert the 4.7 songs with the VST plugins into 7.2 songs?
Would it make sense to open the 4.7 songs with Logic 5.5, then save again and re-open it with 7.2?
all help is welcome

Hi,
I realized that Logic uses AU now but how can i convert the 4.7 songs with > the VST plugins into 7.2 songs?
You would have to have EVERY VST plugin available also as an AU plugin.And it still probably would not work,because logic is SO different than what it was in version 4.The code for most of it has been optimized for g5 and Intel processors,which weren't around in version 4.That alone will change it too much to just open it up straight away.
I would open the old version,if possible,on the old logic version,and then render each MIDI into audio,and get the settings for each plugin.Tons o' work,but if you really MUST do this,to me,it's the only way to ensure it plays back the same as before.
Personally,I like to render each track after a final mix into it's own track,with FX included except for reverbs/delays,as an additional copy of the song.Afterwards,I can playback these copies,all at 0dB on their respective faders,and get a very close facsimile of the mix.I just have to add the reverb and delay effects,and I'm there.
