Not enough space to upgrade to Big Sur in VMWare Fusion?

[Doc69]

I'm trying to upgrade a Catalina VMWare VM to Big Sur beta. But when I run the installer I get a message saying that the disk doesn't have enough free space. 'Get Info' says the disk is 42GB with 15GB free. The installer says it needs at least 20GB free space. However, I tried to increase the size of the disk to 75GB via VMWare's HD settings, as well as checking 'pre-allocate space', but it made no difference. As soon as I boot up the VM, it MacOS still says the disk is only 46GB, but the actual VM file has increased to 80GB. Any ideas?

You have to manually increase the disk size inside the virtual machine once you’ve enlarged the disk in Fusion. That part is not done automatically.

What version of Fusion? Only Fusion Tech Preview supports Big Sur.

Direct Link to .dmg

OK, thanks. I managed to increase the partition in Disk Utility.

Thank you for the link. I'm using 11.5 Pro. Can the Tech Preview be installed side by side with the regular version, i.e. so I can switch between them, or will installing the Tech Preview remove 11.5?

Don't know. I'll check.
Checked. It installs side by side. I installed in Catalina and all is ok

VMWare is the best software of installing Catalina and Big Sur to a physical disk faster and easier.
