Use cp command and following option  -parents       Form the name of each destination file by appending to the target       directory a slash and the specified name of the source file.  The       last argument given to `cp' must be the name of an existing       directory.  For example, the command:              cp --parents a/b/c existing_dir         copies the file `a/b/c' to `existing_dir/a/b/c', creating any       missing intermediate directories.

Create failed for User 'TMS'. (Microsoft.SqlServer.Smo) User, group, or role 'TMS' already exists in the current database. (Microsoft SQL Server, Error: 15023)   To fix this there are two different methods depending on the version of SQL Server you are using.
