Is second Diagnostic agent required in Managed system?

Hi All,

I am going to install the Solution manager 7.1 with two ( Dev, Prd) system landscape. Managed systems in the lanscape are ERP ( Dev,Qas,Prd), Portal( Dev,Qas,Prd), BW ( Dev,Qas,Prd). I want to connect all managed systems to Two Solution managers(Dev,Prd).

My doubt is it possible to connect two solution managers ( Dev, Prd) with single managed system Diagnostic agent ?
