Script baseado na resposta de Joe ( desanexar, copiar arquivos, anexar ambos ).
- Execute o Managment Studio como conta de administrador.
Não é necessário, mas talvez o erro de acesso negado na execução.
- Configurar servidor sql para executar xp_cmdshel
EXEC sp_configure 'show advanced options', 1
GO
RECONFIGURE

EXEC sp_configure 'xp_cmdshell', 1

RECONFIGURE

- Execute o script, mas digite seus nomes de banco de dados
