Keeping Syntorial 1 While Installing Syntorial 2? (Need the Old Lesson Packs)

Hi!
Thank you for a great program, and for a genius method for learning the fine art of synthesis! My poor eyes begs me to install the new resizable GUI, but before that I have a question:

Do the old lesson packs (for Z3TA 2 and Massive) work with the new Syntorial 2? There are no better tutorial for the venerable (and in my opinion underestimated) Z3TA 2, and I would like to keep this accessible on my computer.

If not, is it possible to have both version 1 and version 2 installed at the same time (to install Syntorial 2 without uninstalling/overwriting Syntorial 1)?
