SEPM Server failover for multi-site considerations

Hi Guru's,

I'm looking to setup Symantec Endpoint Protect in a multi-site design with Centralized Management.

My requirements are as (Clustering is not an option).

1. There are 2 Data Centers
2. I want to place one SPEM with off box/on-box SQL Server on each data center and want failover functionally.
3. Clients at one data center reports to its own SPEM and Clients on 2nd data center reports to its own SPEM and I want to set up the environment like

1. If SPEM server or SQL server at 1st Data Center goes offline or shutdown in that case all clients shift to SEPM at 2nd Data Center.
2. If SPEM server or SQL server at 2nd Data Center goes offline or shutdown in that case all clients shift to SEPM at 1st Data Center.
3. When any site which was down comes up in that case clients shifts back to its original SEPM server.

I already setup two SEPM with SQL Servers on each Data center with Replication partners and I have tested that when one SQL Servers goes down and then I turn off the SEPM services manually it shifts the client on other server and when Site goes online again its client shift back.

I want to know is there is any way to automate this process..

SEP version is 14.x
