Hey all!
Does anyone have experience with upgrading their portal after switching to named user licenses? We just upgraded from 11.4 to 115. with named users for the first time. Because the licenses are tied to the portal, Pro would be down for the upgrade time. Our first instinct was to have users checkout an offline copy. However, after upgrading, this is the error message users who check out a license got, and we have to manually release the offline licenses:

Taking licenses online is also not recommended by ESRI:
“Before upgrading Portal for ArcGIS, you must ensure all offline ArcGIS Pro licenses are checked in by your organization members. You can view License activity to see which members have checked out their ArcGIS Pro license for offline use. For information about how to check in an offline license, see Check in an offline license.”

Is there a way for users to continue using pro while upgrading? We would like a solution that doesn't require us upgrading after hours or preventing users from using ArcPro.
Thanks!
