I am looking at moving my NMS users to a different server after I
upgrade my current server to v3 from 2.2.2.

I am planning on a somewhat manual move, using a reg hack to change
users from one server to another, so that's not a concern for me.

Question though, can I leave my current server have the agents talk via
edir and have the ones I install on the 'new' server talking via ldap?

Looking at changing to ldap so I can enable ssl for mobile devices, so
can I have one server using edir and another using ldap?
