I just did a flash-cut migration

I am going to use COBRAS to migrate from windows based unity 7 to unity connection 9.X. &nbsp; I have a couple questions about the use of COBRAS:<br />
<br />
1. &nbsp;When I run the COBRAS export utility on my windows based unity 7 server, is this safe to do during production hours while the system is taking calls?<br />
<br />
2. &nbsp;When I install the new unity connection 9.X server, I would like to give it a new name and IP Address so both unity servers can be online during the migration. &nbsp;When I run the COBRAS import on the new unity connection server, does it matter if the name and IP Address are different from the name and IP address from the server the export was done from? &nbsp; <br />
<br />
3. &nbsp;Lastly, once I run the import on the new server, what happens? &nbsp;Is this server now the one answering calls, the ones with the active subscriber mailboxes, the one integrated with call manager? &nbsp;Or is it still the old server doing all this at this point?

I am going to use COBRAS to migrate from windows based unity 7 to unity connection 9.X.   I have a couple questions about the use of COBRAS:

2.  When I install the new unity connection 9.X server, I would like to give it a new name and IP Address so both unity servers can be online during the migration.

Migrating from Unity 7 (windows based) to unity connection 9

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.
