Unity 7 to Unity Connection 8

Question

this is a design question and best way to go about doing this:
we have Unity 7 voicemail only in it's own domain on box exchange. we have a total of 5 servers like this connected together around the world.
we want to move to Unity Connection HA at all thye sites and network digitally. We want to integrate to their existing corporate domain. we must preserve greetings and passwords and callhandlers but not voicemail. what and how do we do this.

Answer 1

COBRAS cannot maintain passwords since Microsoft AD stores them in a one-way hash. Cisco's documentation says this:
Passwords for Cisco Unity web applications cannot be exported because they are stored in Active Directory. When you create new user accounts by importing data, every account will get the same password, which is the password in the template that you specify when you import data.
You can have internal user accounts in Unity Connection; or syncronize them to UCM or Microsoft AD through AXL or LDAP respectively after import. Unlike Unity, Unity Connection is read-only with LDAP so the schema extensions are no longer relevent.
I'm not sure what your migration strategy is; however, it is possible to digitally network a Unity 8 site (i.e. you would have to upgrade those first) to Unity Connection 8 site. The Design Guide has a whole chapter on this: Migrating from Cisco Unity to Cisco Unity Connection 8.x. You may want to spend some time reading that and deciding on the best course of action.
