Detach published database from one server and attach to another

Hello,

I need to move the replicated database from publisher to another server. It is on SQL 2008 Ent Edition. The server name will be different.

Do I have to drop publications (they will refer the old server name)?

Do I stop distribution agent and log reader agent?

Do I migrate Distribution database?

Do I disable database for replication to be able to detach and attach?

Please help

Thanks,
