Studio edition - does it still use the 'old' EQ instead of ProChannel?

Can anyone using the Studio Edition confirm that the built-in track EQ FX are the same as in 8.5?

I have some projects from 8.5 that have EQ settings that are part of the 'built-in' FX, which is based on the Sonitus EQ, and I'd rather keep them this way in X1 if possible.
X1 Producer tries to convert these to replace these with Pro Channel instead, but I don't want that to happen as I prefer to keep some of these projects as they are.  And yet I'd like to continue working on these within X1 as I am finding that the X1c patch is working well for me, but I'd still like the option of being able to slip back to 8.5 and converting the built-in FX would not allow that without losing settings.

I wonder if it's possible to have the Studio Edition installed alongside Producer Edition?  More importantly, I wonder if it's possible to use some of the other Producer FX (such as the VX-64, VC-64 and PX-64) within the Studio Edition if I have them both installed?

Thanks Randy.

I'm almost tempted to evaluate the Studio version and see if I can answer the remaining questions I have that way.  It seems silly to have to go to those lengths to be able to have the option of using the old built-in EQ instead of Pro Channel.  I'm not against Pro Channel and will use it on new projects, but I wish it there was an option in Producer X1 to use either one...
