On the very last step of upgrading my Enterprise system from 10.7.1 to 10.8.1, the data store fails to configure. It seems to install fine. The error message appears after signing into the data store web url and providing the server credentials.
Attempt to configure data store failed. Caused by: Database upgrade failed for relational data store. Caused by: Could not find home for relational data store binaries 'E:\arcgisdatastore\pgsql10.6'
This appears after the prerequisite check comes back 'Ready for upgrade' for both the relational data store and the Tile Cache (not used).
It seems like the data store upgrade process is confused because I'm not upgrading from 10.6 and it's looking in the wrong folder for the binaries. I'm doing the Enterprise upgrade on IIS server 2019, the server and portal are on separate machines. I successfully upgraded Portal, it's web adapter, Server, and it's two web adapters.
