After I run a SSIS package which is a "Trasfer SQL Server Objects Task", the database users has lost all mapping to SQL server login. I've tried various options inside the package, however, to my surprise, sometimes the user settings at SOURCE database is lost! I won't suppose to change anything in the SOURCE database after running a data transfer... Anyone knows what's wrong? Thanks in advance! Options: DropObjectsFirst - TRUE IncludeExtendedProperties - FALSE CopyData - TRUE ExistingData - Replace CopySchema - TRUE UseCollation - FALSE IncludeDependentObjects - TRUE CopyAllOBjects - TRUE CopySqlServerLogins - TRUE/FALSE (both tried) CASE 1: CopyDatabaseUsers - TRUE CopyDatabaseRoles - TRUE Result - the user-login mapping at destination DB is lost. CASE 2: CopyDatabaseUsers - FALSE CopyDatabaseRoles - FALSE Result - the user-login mapping at SOURCE DB is lost.
