Credentials for Remote Database Upgrade
Use the Credentials for Remote Database Upgrade page of the SQL Server Installation Wizard to specify a database login to a remote report server database.
If you are upgrading a report server database on a remote Database Engine instance, and you are running Setup under credentials that do not have database update permissions on a remote instance, you must enter credentials that Setup can use to connect to and modify the report server database.
Specifies a SQL Server database login that is used one time during an upgrade operation to connect to the Database Engine instance that hosts the report server database. The account must have permission to update the report server database schema.
Required if the credentials you use to run Setup do not have sysadmin or database owner permissions on the report server database.
This value must be specified if you are upgrading a report server that uses a remote report server database to store application data, and the credentials you used to run Setup do not have sufficient permissions on the remote server.
The password for the login or an empty string if the login does not have a password.
