License upgrade migration concerns

We are looking to expand our RConnect 20 licenses today in GCP (RStudio Connect for GCP) to 100 licenses, and we have a couple concerns regarding how this migration should be done to not impact the current structure we have today.

Our VM with 20 licenses already has SSO integrated and there are some shiny applications already being used and leveraged. We would like to upgrade this instance license without impacting the current work already done.

Can you suggest the best path for us to do that?
