We are upgrading our QC server to ALM11.52 and our SQL-Server to SQL2008. We are also migrating all of our Databases from a SQL-Server 2005 instance that was using "Windows authentication" to a new SQL-Server 2008 insance the we want to use "SQL-authentication" with.

Is there an easy way to switch this? When we look at our tables for our old Project Databases, each one is prefixed with "dbo." — I guess that means "Windows authentication"?

On our new server (we did a NEW creation of the qcsiteadmin_db with SQL-authentication), we created a new project and looking at the tables for that database, each table is prefixed with "td.". This must mean it is using "SQL Authentication", since we now have a user, "td" in SQL Server that was created by QC when we installed it.

Your assumptions are correct about the ''dbo.'' and ''td.''. They imply the ''ownership'' of the DB and tables in it and are in fact a clue to whether the QC/ALM project was setup to use ''Windows-authentication'' or ''SQL-authentication''.

Make sure first that you have a backup of your project DB(s).

DBO -> td - DBO (Win-auth) to td (SQL-Auth)
---------
You can switch from one to the other by running this simple SQL command (stored procedure):

To switch Ownership from DBO (Win-auth) to td (SQL-Auth),
Run this SQL from a query window in SQL-Server Management Studio (focused on your project DB):

***sp_MSforeachtable @command1=''sp_changeobjectowner '?', 'td'''***

[this command will cycle through all tables in the project]

Then follow with these 2 commands to ''fix'' the TD user (tie the td user in the DB to the one global to SQL-Server):

***EXEC sp_change_users_login 'Report'***

***EXEC sp_change_users_login 'Update_One', 'td', 'td'***

td -> DBO - td (SQL-Auth) to DBO (Win-auth)
----------------------------------------

---------

To go the other way, switch Ownership from td (SQL-Auth) to DBO (Win-auth):
run this SQL:

***sp_MSforeachtable @command1=''sp_changeobjectowner '?', 'dbo'''***
