Perhaps a correlary script to disable contraints and triggers when copying large amounts of data from one database to another is
sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"
go
sp_msforeachtable "ALTER TABLE ? DISABLE TRIGGER all"
go
sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"
go
sp_msforeachtable "ALTER TABLE ? ENABLE TRIGGER all"
go
