Migration Symantec Endpoint Protection 11.0 to Symantec Endpoint Protection 12.1.4

Hi,

I am a new user of SEPM and I have a few questions about the migration of SEPM 11.0 to SEPM 12.1.4.

I want to install 12.1.4 to a new host with a new adress IP.

Can I Install my new server while my server is always in production ?

Can I use the replication mode or the disaster mode ?

For my clients (110 computers), this migration will be automatic or no ?

Thanks for your help
