• Recriar chaves estrangeiras na tabela filha
• Script a definição da tabela EPOEvents
• Fazer backup do banco de dados EPO
• Reduzir arquivos de dados no grupo de arquivos PRIMARY
• Fazer backup do banco de dados EPO
• Solte o banco de dados EPO
• Formatar unidade J
• Restaure o banco de dados EPO com MOVE
• Relocalizar TempDB para Drive Q
• Iniciar serviços de aplicativos EPO
• Confirmar que o EPOEvents está preenchido
