cubase 10 update vs upgrade

What is the difference between:
updating and upgrading from cubase10 pro to cubase10.5 pro?

Updating = You stay within the product range, but go to a newer Version. For example from Pro 9.0 to Pro 10.5, From Elements 10.0 to Elements 10.5
Upgrading = From a lower product range to a higher product range. For example from Elements 10.0 to Artist or Pro 10.0 or 10.5
So From Cubase 10.0 Pro to Cubase 10.5 Pro is an update, not upgrade.

Thanks for clarifying!
