So upgrading Portal in customer's staging environment took almost 3 hours to complete. To minimize the maintenance window required for the production upgrade, I'm curious if we can go ahead and complete the upgrade of the hosting ArcGIS Server and additional federated ArcGIS Servers and their respective web adapters while Portal is upgrading.
Esri's docs "recommend" doing the upgrades in a specific order, but don't explicitly say you can't do them in parallel.
Thanks!
