If you receive a “Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.TransferDatabasesUsingSMOTransfer()” or “End of package execution.” while trying to copy a database on the MSSQL Server.
The reason can be that a file with the new Database name already exist on the filesystem. We encountered this when we renamed Database X to X_Old, and tried to copy database Y to X. This cannot be done, because database X_Old is still associated with the filename X.
Either delete the conflicting database, or rename the file on the file system.
