[cisco-voip] Unity Connection upgrade from 7.1(3) to 9.1(2)

[Rasim Duric]

Thank you James. I can conclude that the statement from the document refers to COBRAS. I'll be using DRS so shouldn't be concerned.

Rasim, 

I did an upgrade from Unity 7 to Unity Connection 9.1.2 a couple years back, and I think I know what you mean. 
For my upgrades, I wanted to build Unity CxN in parallel with my production Unity 7, so that I could do a migration at my chosen pace. 
For this I went with COBRAS. It’s been a while, but I don’t remember whether or not this jump allowed for a backup and restore type of upgrade. 
But it sounds like that’s your plan of attack. 
For COBRAS export from Unity, use breifcase mode. This does not require network path from source and target server. 
also, does not make any changes to source sever the way "hot mode" does. 
For what its worth, here’s some information on what COBRAS gets you for this type of upgrade. In case you change your mind… 

COBRAS gets most data for the following parameters: 
Call Handlers 
Subscribers 
Interview Handlers 
Directory Handlers (will be called Name Loop Handlers in UC) 
Public Distribution Lists 
Schedules 
Routing Rules (typically recommending for restores only, not migrations) 
Custom Key Mapping Coversation Data (UC to UC restores only) 

COBRAS does NOT get data for the follwoing: 
Class of Service 
Restriction tables 
Locations 
Contacts ( SMTP/AMIS/Bridge/VPIM subscribers) 
Holidays 
Sys Config Data ( LDAP integration, IMAP login, RSA config, Advanced settings, etc.) 
Subscriber Templates 
Call Handler Templates 
Password policy information 
Securty messages from older UC revs.

Hello everyone, 



I'm planning to upgrade our two Unity Connection servers 7.1(3)ES11 to 9.1(2)SU3. In the Cisco document at this URL: http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/9x/requirements/9xcucsysreqs.pdf , page 30, you can read the following: 



During the migration, only user data and, optionally, voice messages are preserved. System-level configuration data (for example, templates and classes of service) must be manually configured. 



I'm migrating CUC 7.1(3)ES11 from one physical server to another physical server (compatible with 9.1(2)SU3 specs). The plan is to install 7.1(3) from scratch on the new server and then restore the old server via DRS. After the 7.1(3) is up and running on the new server, perform the 9.1.(3)SU3 upgrade. I think all data should be preserved including the templates, the Class of Services, etc. in my case. 



When would someone actually experience the above statement from the Cisco document? What else is not preserved? 



If anyone has done a similar upgrade, I'd like to hear any tips and tricks or issues you ran into. 



Thanks.
