Tungsten upgrade installation is not able to connect to the existing database

Issue:

When upgrading the Kofax Totalagility version from 8.0 to 8.1, the issue of connecting to the existing database(SQL Server) occurred. A connection was successfully established with the SQL Server, but then an error occurred during the login process.

Below is the error message:

BPM Error: 1 : Fatal error Occurred when installing, application will exit Microsoft.Data.SqlClient.SqlException (0x80131904): A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The target principal name is incorrect.) ---> System.ComponentModel.Win32Exception (0x80004005): The target principal name is incorrect
   at Microsoft.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, UInt32 waitForMultipleObjectsTimeout, Boolean allowCreate, Boolean onlyOneCheckConnection, DbConnectionOptions userOptions, DbConnectionInternal& connection)

 

Resolution:

The reason why the issue occurred is that the Setup.exe file in the newer version TotalAgilityInstall folder failed to find the right SQL server.

1. Navigate to the location under:

    \\<The Folder Where TungstenTotalAgility-8.1.0 Installer Is>\\TungstenTotalAgility-8.1.0\TotalAgilityInstall

2. Find Setup.exe.config

3. Change the value for Server to the SQL Server Name.

4.  Save it and run Setup.exe again.
