Increasing disk of ISE VM. Have to reinstall?!

We're looking to upgrade from 2.0 to 2.4. The VM doesn't meet the minimum specs for 2.4...

No problem, we'll allocate more resources in the hypervisor. Then I read this:

"If you increase the disk size of your virtual machine after initial installation, then you must perform a fresh installation of Cisco ISE on your virtual machine to properly detect and utilize the full disk allocation."

So does an upgrade not constitute a valid installation operation to detect an increase in disk size? Anyone have any experience with this?

Here's the link to the 2.4 upgrade guide with the text I quoted: https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/install_guide/b_ise_InstallationGuide24.pdf
