Must I delete previous Cubase versions

Im Updating to Cubase Pro 10. Must I delete my previous versions after updating. I preserve for now my Mac 7.5 and my 9.
My Mac its kind of full.

Thanks in advance

You can keep previous installations. I have kept 8.5 as it’s the last version that ran 32bit plugins reliably on my machine and that is important to me for backward compatibility. Pro 10, even with bridging is hopeless with anything 32bit. I suggest if space is tight, you eventually remove one of the older versions to suit your cubase use, but make sure you are completely confident with Pro 10 first.

Thanks ¡!
