When I execute "Upgrade Content Manager database.ps1" script on powershell I got the message "Database is up to date or has invalid version". Same is the outcome for "Upgrade Topology Manager database.ps1". But "Upgrade Content Data Store.ps1" script for upgrading Tridon_Broker and XPM_database worked perfectly fine. I checked the table TDS_DB_INFO and it shows the db_version not updated for content manager and Topology manager database.
TDS_DB_INFO :Content Manager Database,Topology Manger Database DB_VERSION = 8.1.0.0
TDS_DB_INFO: Tridion Broker Database,XPM Database DB_VERSION = 8.1.1.0
