Hey, So I bought cubase 10.5 Pro last year and have decided to upgrade to 11 Pro while it’s on offer. My question is will all my tunes and vst’s work absolutely ok in cubase 11. Probably a silly question but I’d rather ask before risking losing anything.
Cheers in advance 
Everything should be just fine in 11. Plus you can always leave 10.5 (or any older versions) installed as an insurance policy. Projects are both forward & backwards compatible between versions. You can even run both versions at the same time.
