TF255324: The database that you specified cannot be created because a database already exists with that name. The database name is: {0}. The server hosting the database is: {1}.  You can use one of the three following options.
    • If the database is a valid database from a previous version of Team Foundation Server and you want to upgrade it, you must use the Upgrade from Previous Version Wizard.
    • If the database is a valid database from the current version of Team Foundation Server and you want to use it, you must use the Application-Tier Only Wizard.
    • If the database is a valid database used by another Team Foundation Server instance and you wish to create a new database, you must use the advanced wizard to supply a different SQL Server instance or database label.
For more information, see the readme file and the installation guide for Team Foundation.
