Apple Logic Pro /LogicExpress Discussion

Hi folks!

There appears to be a similar thread to this, but it seemed to be more hardware centric and going from Mac to Mac.  My question is a bit different.

I was a Logic Platinum 5.5 user on PC for several years.  I recently picked up an Intel Mac Book Pro that I'd like to run Logic on when I'm not working on my PC desktop.  I'd now like to go back and convert my old 5.5 projects. The end goal is to get up to Logic Pro 9, but I've got to first get past this huge project conversion task (about 70 projects).

So here are my questions: 

- What's the minimum version of Logic I need for the conversion on a Mac/Intel machine? Version 7? 8? 9?  

- What flavor do I need minimally: Pro or Express?  Would it matter given that I also utilized EXS24, EPV88 and EVOC20 plug-ins? Would Express keep these settings through the conversion or just throw those settings away?

- Not clear to me if 7.0 works on Intel.  If not, can I still get the Universal Binary/Intel upgrade from somewhere if I could only find a copy of 7.0 to buy?  If so who has the upgrade? I can't find anything on the Apple site about it anymore.

- Will the "built-in" plug-in settings carry over (EVP88, EXS24, etc.)?  And if not, will I at least be able to save a Logic Preset file (.PST) from 5.5 and load the settings that way?

This information would be a BIG help!  I've been researching this for several days now and I still feel I have clear direction.  I'd like to get moving on this as soon as possible so I can include some of these songs in near-term as well as future project work and it's just too risky to put any more effort into such an obsolete version.

Thanks much!

John
