Hi,
There are two methods to move Symantec Endpoint Protection Manager (SEPM) from one machine to another:
Method 1: if the SEPM server keeps the same IP and host name, you can refer to "Best Practices for Disaster Recovery with the Symantec Endpoint Protection Manager"
http://www.symantec.com/business/support/index?page=content&id=TECH102333&locale=en_US.
Method 2: if the new SEPM server has a different IP and host name, there are two alternatives:
1. Use replication to install a new SEPM and keep the policy the same with old SEPM. See "How to move Symantec Endpoint Protection Manager from one machine to another"
2. Install a new SEPM, then use the Sylink file to establish communication between the new SEPM and the existing SEP client.
