add additional SEPM to existing site with existing embedded DB

Hello Guys,

I was searching about if I can add another SEPM to the existing site that already have one SEPM that have an embedded DB, but when I try to connect to the embedded DB from the new SEPM with the following parameters : existing-SEPM-IP\sem5 , prot : 2638, DB name: sem5, DB user : DBA, so i think I got everything right but i am doubting is this is even possible?

Best Regards.
