I Move SCCM2012 from one server to another (Site recovery on the new server from Backup).

Database and SCCM were on two diferent servers in the old config.

Database and SCCM is on the same server now (in the new config, after migration).

As a whole all working fine, but I have problem:

1. In the new config, in SCCM setting, I have Site System Server with 3 roles (010 on the screenshot below). This server is not useful and this server does not exist now. Database was on it in the old config. 

2. Also, in the new config, I have Primary Site server which has all roles including Databae (04 on the screenshot below):

I can't delete Site System Server (010) because it has 3 roles.

I can't delete any role on this server because delete button is not active on any role:

How I can delete not useful Site System Server (010)?
