SEPM clients list migration to new server problem

Hi all

I setup a new server & setup a SEPM.

When I run old server SEPM it show failer to connect to the server,

Run serveices,msc & can't start SEP &SEPM services,

Repaired SEPM but same problem,

I have SEPM login & password,

Can I copy client list to new SEPM without login? (2 server SEPM are same version)
