Move data from 4.2.3 to 4.2.5

I just installed a virtual 4.2.5 Zenoss server into our VMWare stack from the pre-made virtual Zenoss download.

Firstly, I can't find the actual user name and password to logon to the CentOS server.

Second, how do I move my data from my old 4.2.3 server to my new 4.2.5 server

Thanks.
