Nuendo files recognized by Cubase

Would anyone know the earlist versionof Nuendo that can be recognized by Cubase 10?


To clarify: I had been using an ancient version of Nuendo (1.6) on an ancient desktop (XP/Pentium 4)!!

I will be purchasing a new desktop w/Cubase 10.

I was planning to export all my Nuendo tracks to .wav files, but, alas, my current computer died before I was able to!

Thanks for your assistance!
