Hi Amit,
If possible provide more info, are you moving from server 2003 to 2008? changing only IP address or hostname as well? Which version are you planning to install?
With this info we can give you one of the best possible solution.
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"
SEP 11.x: http://www.symantec.com/business/support/index?pag....
SEP 12.1: http://www.symantec.com/docs/TECH160736
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"
http://www.symantec.com/business/support/index?page=content&id=TECH104389
Note: Replication is an option, but its better not to go for that. Because if you do replication and remove the old server that is the Primary SEPM , in future if you want to do replication you will not be able to do so.
2. Install a new SEPM, then use the Sylink file to establish communication between the new SEPM and the existing SEP client through sylink replacer tool.
Note : Sylink replacer tool is most commonly used option because it's easy to use.
