Upgrade composer 2.6 to 3.0

Hi boys

I need upgrade my  composer from 2.6 to 3.0, now composer is active on windows 2003 server with vcenter server.  My view connection server is 5.0

I have moved the composer db on windows 2008 sql.

It is possible move the composer, separatly from vcenter, on new window 2008 R2 server with new ip address and hostname? 

I have read the vmware view upgrade 4.6, but i have big problem for identify where i need configure the view connection to talk to new location of composer .....

Thank

Fabio
