Sql-server – Order to restore system and user databases

This should solve your problem:

http://msdn.microsoft.com/en-us/library/ms345408.aspx

That link has instructions to move system databases from one instance to another, if you move all databases as is (including user ones, for which you can copy the file, however you will need downtime, or if your databases are on a SAN you can use a SAN snapshotting software), the SQL Server will come up with everything intact.. Keep in mind that if you have a named instaces (NAME1\NAME2) then the NAME2 should be same for the destination instance..

You will have to attach the MSDB DB under a different name like 'jobsdb' and pull the jobs out of jobsdb. The jobs will be stored under jobsdb.dbo.sysjobs and the job steps will be under jobsdb.dbo.sysjobsteps. They can be joined by the job_id column.

The schedules can be found under jobsdb.dbo.sysjobschedules joined with jobsdb.dbo.sysschedules on schedule_id.

The rows can be added into your current msdb using a insert-select, or by using the stored procedures: sp_add_job, sp_add_jobstep, sp_add_jobschedule, sp_add_jobserver.
