Reinstalling SEPM 12.1.5 wihtout recovery files

Hi,

My server HDD crashed where SEPM 12.1.5 is installed on. I have previously made a database(embedded) backup. I plan to do a fresh installation on the new HDD and my question is:-

Can my clients (100 clients) still communicate back with the new SEPM after i restore the DB? Problem is i did not make a back up on the recovery files, hence the management server will not have any previous configurations.

Please advise.
